Modern Cars Wreak Havoc on Radar Detectors. Here's How Escort Adapts
Escort Radar, one of the big brands in the radar detection biz, has been under some scrutiny this year as customers and reviewers reported suboptimal performance on the $800 Redline 360c—Escort's flagship. Today, it's dropping a big firmware update to address those complaints. I've now had the chance to test this new firmware and speak with somebody at Escort, and came away with some insights you might find interesting, even if you don't run one of these on your dashboard.
All radar detectors can be affected by the radar-powered collision avoidance systems of modern cars. And since more of those cars are on the road every year, filtering those signals out becomes a bigger challenge for detector engineers.
As most of you reading this probably know, radar detectors are designed to alert you when cops are measuring, or about to measure, your speed. They're legal throughout the USA except in Washington, D.C., and the state of Virginia. Since we don't write about these too often, I'll quickly rip through some high-level context and then run down Escort's new update.
A radar detector is basically a radio receiver. When police post up somewhere to collect ticket money, they'll often point a radar gun down the road, which shoots a radio wave at oncoming cars. When that wave bounces back to the radar gun, it does a little math and tells the cop the target's speed. Many American police use K- and KA-band radio waves for this purpose. The reason a detector is a viable countermeasure to this is that K-, KA-band, and other such radio waves, shoot wide beams that kind of spill out beyond one specific target—think, kind of, like a shotgun versus a rifle. So you can be driving down the highway, and a good detector will be able to pick up a KA signal before police have made visual contact, giving you a little heads-up. Adobe
Another speed-measuring tool police use is laser—this is much harder to get any forewarning on. It's faster and more precise; while a good detector will have an alert that you're being hit with a laser, your speed will already have been measured at that moment. Some radar detector brands, including Escort, sell a supplementary device sometimes called a 'laser shifter' that's supposed to be able to confuse such signals, but that's not nearly as widely legal.
Interestingly, radio waves are regulated by the FCC, while laser is regulated by the FDA. This is partially why the rules on the usage of both types of signals are inconsistent with each other.
After polling radar review sites, forums, friends, and fellows in a California car club I belong to, I found that people willing to splash out on a high-end detector often favor the Valentine One, Uniden, and Escort brands the most, with Whistler and Radenso also getting fairly frequent mentions. However, the high-end Escort Redline 360c has fallen out of favor lately, mainly due to an apparently weak response time. It came off Vortex Radar 's recommendation list for this, false alerts, and general bugginess at the beginning of the year. You can update an Escort device via your phone's internet connection or with a computer using free official software. This particular update is a big one—expect 30 minutes or more to complete it.

The Escort Redline 360c is physically the same unit that was released in 2020, but has received quite a few firmware updates since then—the device typically gets one or two over-the-air updates per year.
Broadly speaking, American Police speed-measuring technology has not changed all that much in recent years and decades. But traffic and enforcement techniques have, and both of those factors are significant in the radar detector world for separate reasons.
First, let's talk traffic—blind-spot monitoring, radar cruise control, and similar safety systems have had a huge spike in prevalence in the last 10 years. That's created a lot of false alerts for radar detector users and has been a big focus for detector engineers. Joe Sherbondy, the Director of Escort's Radar Detection Products, told me this phenomenon is called a 'CAS blast' in the biz—CAS being a blanket term for collision avoidance systems, and blast referring to the barrage of warnings a detector would set off any time it got near a modern car. Refinements to compensate for this are a continuously ongoing process at Escort, Sherbondy told me, and I'm sure the same would be said for other brands.

Secondly, there's the 'quick-trigger' method of speed enforcement that detectors need to contend with. Police are aware of radar detectors' ability to pick up on Ka-band radio waves before they can spot a potentially speeding car, so sometimes instead of simply pointing a radar gun down the highway and leaving it running, cops will manually pull the trigger, theoretically getting a ping before a detector can see it. But as Mr. Sherbondy explained it to me, that only gives the gun user an approximate idea of your speed—they need to hold the trigger down for a period of time to get a confirmed reading and write a ticket. Theoretically, if your detector could pick up the quick-trigger ping, you could still slow down enough to slip below the get-fined threshold for police attention.
As for how a company like Escort figures all this out and proceeds with research and development, Sherbondy told me that for his outfit, the main source of bug squashing prioritization is a combination of scanning user forums, the brand's Facebook page, and feedback his customer care team gets by phone and email. I found a forum post from just a few months ago in which Sherbondy himself tossed up on a radar detector forum explaining an update and soliciting user feedback.
So, some actual product testing is done in part by customers, while Escort also maintains its own closed network of beta testers. Of course, it does its pre-release R&D in a lab. In response to requests for transparency, the brand just released a white paper explaining its testing methodology along with today's just-announced firmware update. You can take a look at that here: Escort Redline360c July 2025 Firmware-Update WhitepaperDownload Escort-Redline360c-July-2025-Firmware-Update-Whitepaper
This interesting document showcases how the Redline 360c's enhancements were measured and includes some insights on how speed is measured by law enforcement in general.
Here's what Escort claims to have improved with its July 2025 firmware update (version 1.17), per release notes: Improved Filtering & Alerts: Modern vehicles use an array of radar systems that can confuse traditional radar detectors. Redline 360c is now a master of ignoring these invalid radar signals, with up-to-date filtering that can recognize automotive safety systems like adaptive cruise control, blind spot monitoring, or emergency braking systems. This allows the detector to focus on and identify actual police radar signatures, ensuring that drivers only receive alerts that matter.

I have not run a radar detector since I was in high school, when I thought I was hell on wheels in my 160 horsepower base-model FC RX-7. Unfortunately, it did not keep me from getting cited for driving like a dick (I forget what the actual infraction was) or running an aftermarket exhaust (in hindsight, straight pipes might have been a little obnoxious for my suburban neighborhood). Both tickets were deserved, anyway.
Nowadays, I just kind of drive at what I consider a socially acceptable speed for the road and conditions, and have mostly managed to avoid the scorn of law enforcement. However, I did find some significant satisfaction just watching the watchers, so to speak, with the Redline 360c on my dashboard and Escort's accompanying 'Drive Smarter' app on my phone. I quickly realized it was not practical to get images of the Redline 360c in use—my camera's shutter speed couldn't capture the screen accurately. But Escort's render makes it a lot easier to understand what the device looks like in action. At least you can see how the alert looks on the charging outlet (which has a secondary USB output).

After a few days of real-world testing in rural New York, my impressions are mostly good. I ran it with and without the update, and to be honest, I thought it worked pretty darn well on the old firmware, too. But just last night I went out, running the new firmware, and can confirm that in about two hours of cruising, I encountered four speed traps, and all four times the Redline 360c lit up before I had eyes on the cop. (Yeah, New York state has an intense police presence even 100 miles outside NYC.)
The directional warning worked, too—it wasn't practical to document, but it was easy to watch the forward arrow light up, then the side I'd pass radar on, and then the rear light stayed on as I drove away from a lurking radar emitter.
What it did not detect were the five other LEO vehicles I clocked in traffic with me over the same drive loop. I suspect they were not emitting any speed-reading radar while traveling—it's a radar detector, not a police detector.
As far as early warning on speed traps, I was impressed with what I saw. The Drive Smarter phone app wasn't quite as satisfying—I had some inconsistent Bluetooth pairing performance. And while it's supposed to be able to get local speed-limit data from the internet to project onto your detector for reference, mine could never find this info. I didn't experience any false alerts at all.
The Escort Redline 360c is physically and functionally a nice piece of tech. The windshield clamp is incredibly solid, and the magnetic attachment base hooks up with a slick snick. I really like the Knight Riderish sweeping red line animation it does by default, and having a mute button on the power cord is nice for easy reaching. I can't say if it's worth the price premium over more basic units, but it's been dead-on right and reliable in the days and hours I've been real-world testing it.
A radar detector on your windshield invites some social judgment. I mean, the whole point is to enable speeding, right? My perspective is that there's a pretty big gap between exceeding some speed limits and reckless driving. Posted limits, unwritten limits, and dangerous limits are not always the same. Cruising at 70 mph on I-87 in New York is technically illegal, but largely safe, and certainly socially permissible. Weaving through traffic with a huge speed delta over other cars? That's where you start to become a menace—and a radar detector won't shield you from getting busted for that kind of activity anyway.
Carrying excessive speed where it's not appropriate is dangerous and rude. But there's nothing wrong with having some intel on where speed traps might be hiding.

Abundance in Orbit—The Case for Democrats Reclaiming NASA's Bold Vision
Advocates for ideas and draws conclusions based on the interpretation of facts and data. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. NASA is in crisis. The space agency that once embodied American ambition—proof that our government could do bold things and solve hard problems—is now unraveling before our eyes. More than 2,000 senior staff are heading for the exits. Without help from Congress, science programs will be slashed to the bone. And a permanent administrator is nowhere in sight. Unless a different vision emerges—one rooted in public ambition and scientific leadership—the U.S. risks forfeiting a field it once defined. The good news? There's a growing hunger for that kind of vision. The success of the "abundance agenda" in other policy arenas has shown that voters are ready to believe in big things again. Space should be next. Jared Isaacman, the billionaire entrepreneur and civilian astronaut many expected to lead NASA, had potential to offer exactly this kind of leadership—until his nomination was scrapped under White House scrutiny. A NASA logo is displayed at the entrance to the Mary W. Jackson NASA Headquarters building on June 2, 2025, in Washington, D.C. A NASA logo is displayed at the entrance to the Mary W. Jackson NASA Headquarters building on June 2, 2025, in Washington, was graceful in his exit, but his recent commentary has had a clear through-line: space is the high ground, one that gives any country who ventures into it a clear advantage. As Democrats struggle to connect with the American people, with recent polls showing a 30-year low in popularity, now is the time to show the U.S. electorate a path of inspiration. And the rise of the abundance agenda, applied to space sciences, can be a critical way to galvanize support. Ezra Klein and Derek Thompson's bestselling book, Abundance, has shifted the conversation primarily in terms of housing abundance, and recent elections have shown the stickiness of that issue with voters. But Klein and Thompson also have a deeper diagnosis: American innovation systems are broken. Risk aversion in funding the sciences, high administrative burdens and the pressure of scientific discoveries needing to be converted into mass production, are what hold us back. Now, as scarcity politics grips Congress, Democrats can seize the opportunity to do more than defend science—they can champion it. By making the case for a bolder, federally-backed innovation agenda, they can show voters how public investment has always been the engine behind America's greatest breakthroughs. What has been referred to as a stagnating of the U.S. innovation ecosystem, and the "undermining of science in America," should be leveraged by Democrats to promise voters not just greatness, but more. As a guest on Andrew Schutlz's Flagrant podcast, former U.S. Secretary of Transportation Pete Buttigieg outlined how federally funded projects have led to monumental ideas later transformed into usable reality, including the internet itself. Still, the challenge Democrats face is significant. These sorts of projects are costly, and they don't come with any certainty, but that's the point. Unlike the private industry, profit isn't the motivating factor behind our exploration of the unknown. Helping voters see the long-term value of such investments will undoubtedly take work. But we've done it before. In May 1961, President John F. Kennedy promised America the Moon. The endeavor would demand "a major national commitment of scientific and technical manpower, material and facilities ... where they are already thinly spread," Kennedy said. And then, it happened. Beyond international prestige and the assurance of democracy's strength over communism, the Apollo program seeded "spin-off" technologies that reshaped everyday life. Just as important, it proved what government can accomplish when it channels its full capacity toward shared purpose. Even after Apollo, NASA had what was referred to as an "aggressive plan" that would continue to position the U.S. as a leader in the exploration and development of the space frontier. That vision was later shelved, a casualty of budget cuts and shifting political winds. Still, the principle remains: science moves when government moves with it. We saw this again with Operation Warp Speed, where President Donald Trump's Department of Health and Human Services and Defense used a "whole-of-America" approach to bring the COVID-19 vaccine to the masses, and quickly. But this spirit is fading. Republicans have seemingly turned their back on the idea of science as a public good. In response to the president's proposed cuts to NASA Science, every prior associate administrator of Science signed onto a joint letter to the House Appropriations Committee warning of the potential reduction of funds. As Congress grapples with what funds to provide NASA in this new fiscal year, Democrats should ask themselves: can we be the party that reclaims science as a shared American project? Can we speak to voters' appetite for ambition? A promise to pursue abundance—in space, in science, in national purpose—may be the boldest and most unifying offer Democrats can make. Trump has promised voters a path of greatness, but he's steering our science agencies dangerously off course. It's high time for Democrats to chart a better one. Riley L.

Companies from Stanley Black & Decker to Conagra are saying tariffs will cost them hundreds of millions
Companies behind some of America's best-known brands are warning that tariffs will raise costs by hundreds of millions of dollars as Friday's key deadline nears. Firms are gearing up for the long-awaited Friday deadline, when the White House says it will start imposing higher import taxes on foreign countries. Now businesses in a range of industries are saying this shakeup in global trading practices will cost them. Tool maker Stanley Black & Decker said Tuesday it expects an $800 annualized hit from policy changes tied to tariffs. That doesn't include costs in connection with steps the company is taking to mitigate the effects of the levies, according to finance chief Patrick Hallinan. For Marie Callender's and Slim Jim parent Conagra Brands, higher tariffs are expected to raise its costs of goods sold by 3%, equivalent to an annual increase of more than $200 million, CEO Sean Connolly said earlier this month. Most of the Chicago-based company's production is in the U.S., but management says it still has to contend with steel and aluminum tariffs that will raise the cost of packaging. Tesla, led by President Trump's erstwhile ally Elon Musk, said that costs tied to tariffs have increased by about $300 million. Roughly two-thirds of that is tied to the electric vehicle maker's auto business, while the rest is from the energy arm. "While we are doing our best to manage these impacts, we are in an unpredictable environment on the tariff front," finance chief Vaibhav Taneja told analysts and investors on Tesla's earnings call last week. Those pressures extend throughout the auto industry. General Motors said earnings before interest and taxes in the latest quarter suffered a $1.1 billion hit that the Detroit-based automaker chalked up to the net effect of tariffs. Air conditioner maker Carrier Global said Tuesday that it now expects to spend about $200 million to offset the impact of tariffs. The same day, appliance maker Whirlpool said North American sales and earnings were hurt in the second quarter as Asian competitors rushed to export goods to the U.S. in advance of higher tariffs. U.S. consumers haven't yet experienced meaningful bumps to inflation as a result of higher tariffs. That can be attributed to domestic companies currently absorbing cost hikes, but some economists warn that business may soon start passing the increases on to shoppers after this week's deadline passes. As a result, the "core" version of the consumer price index, which excludes volatile food and energy prices, should rise at an annual rate of 3.2% in the third quarter, up from 2.1% in the second quarter, according to Nancy Lazar, Piper Sandler's chief global economist. Foreign exporters have been covering "very little" of the tariffs and have been "getting off easy," Lazar said in a recent note to clients. Still, not every American company is taking a hands-off approach and swallowing the higher costs. Paul De Cock, operations chief at carpet manufacturer Mohawk Industries, said last week that it is implementing 8% price increases. There may be need for further price hikes in the sector if tariffs further raise costs, he said. "We continue to work with customers and suppliers to manage the impact of tariff costs as the situation evolves," De Cock said on the Georgia-based company's earnings call. Mohawk is encouraging consumers to look at domestically produced alternatives, he said. The company is also expanding capacity for quartz countertops made in Tennessee, which will increase the supply of goods not subject to tariffs, de Cock added. For its part, the White House is aiming to soothe companies' concerns about the looming deadline for tariffs, which were a core tenet of Trump's campaign last year. Treasury Secretary Scott Bessent, for example, told CNBC on Tuesday that countries facing high tariff rates can lower them by negotiating a deal with the U.S. "I would think that it's not the end of the world if these snapback tariffs are on for anywhere from a few days to a few weeks, as long as the countries are moving forward and trying to negotiate in good faith," he said.

US-China race takes center stage as Trump defines AI policy
The Trump administration is increasingly framing the race to dominate artificial intelligence (AI) as an existential competition with China to determine the future of the powerful technology. It's a mindset that has permeated the administration's push to define its AI policy, including as it unveiled its action plan on the subject this month. 'The United States is in a race to achieve global dominance in artificial intelligence,' an introduction to the plan from several key Trump officials reads. 'Whoever has the largest AI ecosystem will set global AI standards and reap broad economic and military benefits.' 'Just like we won the space race, it is imperative that the United States and its allies win this race,' it continues. Outside observers generally say the administration is not overstating either the fact of the intense race or the importance of winning it. They compare the battle to the arms race or the space race in decades past. 'It's an AI arms race,' Wedbush Securities analyst Dan Ives told The Hill. 'The U.S., I believe, is ahead of China, but China is not sitting on a treadmill.' The new AI model from the Chinese startup DeepSeek was dubbed 'AI's Sputnik moment' by venture capitalist Marc Andreessen. Sputnik, the first artificial satellite launched into space by the Soviet Union, took the U.S. by surprise and marked the start of the space race between Washington and Moscow. DeepSeek's highly capable model similarly shook the American AI landscape, raising questions for U.S. tech firms about the need for vast investments in computing power and the prospect that Chinese tech firms could eventually surpass them. 'You risk becoming reliant on other countries, and then in a moment of crisis, you may not have access to the technology or software that you need,' Owen Tedford, a senior research analyst at Beacon Policy Advisors, said of the stakes of the AI race. The Trump administration has approached the growing prospect of Chinese AI by pushing for a focus on innovation over regulation, drawing a sharp contrast with the Biden administration. In its 28-page framework, the Trump administration detailed its plan to win the AI competition, with a focus on removing regulations, expediting the construction of data center and energy infrastructure and exporting U.S. technology abroad. After taking office, President Trump rescinded former President Biden's executive order on AI guardrails, while Vice President Vance criticized 'excessive regulation' of AI while in Europe earlier this year. Trump's AI plan looks to boost innovation by taking aim at both federal and state AI rules, directing his administration to slash federal funding for states with regulations deemed too 'onerous' — not unlike the AI moratorium some Republicans unsuccessfully sought to squeeze into the president's 'big, beautiful bill.' The framework also aims to encourage the adoption of American technology abroad, another key aspect on which the administration is differentiating itself from its predecessor on the AI race. The Biden administration took a more restrictive approach toward the export of American AI, primarily through limits on chip sales that sought to prevent the key hardware from winding up in the hands of foreign adversaries such as China. Biden released the AI diffusion rule in his final days in office, placing caps on chip sales to most countries around the world other than a select few U.S. allies and partners. Trump rescinded the rule in May shortly before it was set to take effect. While some Republicans have urged him to release a new version of the diffusion rule, the president has opted to focus on exporting U.S. technology as a means of boosting AI leadership abroad as opposed to limiting China's resources. He signed an executive order Wednesday directing his administration to create an American AI Exports Program that will develop full-stack AI export packages, featuring U.S. chips, AI models and applications. 'There's a belief that maybe by dominating the AI race, if we are able to be technology leaders, China will end up becoming reliant on us instead of cutting it out and forcing it to create its own domestic alternatives,' Tedford said. 'It's an argument that didn't really seem to have much weight in the Biden administration but seems to be carrying the day much more with the Trump administration,' he added. Ben Buchanan, a White House special adviser on AI during the Biden administration, argued in a New York Times op-ed Thursday that Trump is making a 'profound mistake' when it comes to China. His criticism centers on a key decision made last week by the Trump administration to once again allow Nvidia to sell its H20 chips to China. Earlier this year, the U.S. implemented new licensing requirements that limited Nvidia's ability to sell the chips in China. However, the company recently revealed it was filing applications to sell the H20s after receiving assurances from the Trump administration that its licenses would be granted. Buchanan argued the decision 'threatens American dominance' over AI because 'Nvidia's chips will give China's A.I. ecosystem, and its government, just what it needs to surpass the United States in the most critical arenas.' Trump's approach also risks alienating the China hawks within his own party, who have voiced concerns that it could boost Beijing's AI capabilities. Rep. John Moolenaar (R-Mich.), chair of the House Select Committee on the Chinese Communist Party, questioned the administration's decision to allow for H20 sales to China in a letter Friday. 'As the Trump administration has repeatedly stated, the U.S. must ensure that American rather than Chinese tech companies build the global AI infrastructure,' he wrote. 'At the same time, however, we must also ensure that the world does not adopt Chinese AI models trained on U.S. technology.' Another outspoken Republican, Rep. Marjorie Taylor Greene (Ga.), is pushing back on the third prong of Trump's AI plan, which seeks to boost the construction of AI data center and energy infrastructure. The administration has repeatedly underscored the infrastructure needs for building out American AI capabilities, with Energy Secretary Chris Wright comparing the AI race to the Manhattan Project. The tech industry has also ramped up pressure, specifically on the energy front. Anthropic argued in a recent report that the U.S. is 'lagging in bringing energy generation online,' while China is 'rapidly building energy infrastructure for AI.' However, Greene warned Thursday that there are 'massive future implications and problems' with Trump's data center buildout given its potential impact on water supply, while also taking aim at the president's plan to target state AI rules. 'Competing with China does not mean become like China by threatening state rights, replacing human jobs on mass scale creating mass poverty, and creating potentially devastating effects on our environment and critical water supply,' she said.
