Why Do Most Drivers Turn Off Vehicle Safety Systems?
There's a good chance that your late-model car, truck, or SUV has a handful of Advanced Driver Assistance Systems (ADAS). There's also a good chance that you are not using them, as numerous studies have revealed that most drivers find them distracting and annoying due to frequent alerts, perceived over-correction, or unexpected interventions. If you are like most drivers, you get frustrated and turn them off—negating the safety benefits.
To dive deeper into why drivers are shutting off their vehicle's ADAS technology, which includes adaptive cruise control, lane-keeping assist, and automatic emergency braking (often marketed under slightly different names, depending on the automaker), I polled more than a half-dozen drivers to get some additional insight.
My findings were consistent with the published studies. Drivers welcomed the ADAS technology (often paying to have their vehicle equipped with the features), optimistic that it would make driving less stressful and more relaxing. Instead, they frequently found the features intrusive, annoying, unreliable, and startling as they intervened unexpectedly and without warning. While some of the technology, such as Automatic Emergency Braking (AEB)—designed to intervene only in emergencies—could not be defeated, systems that could be turned off were often.
'I must turn off the system continuously,' says Sean Dugan about BMW's Lane Keeping Assistant. 'It's jarring and most of the time—more like all the time—unexpected.' And he notes that things are even worse after the sun goes down. 'At night, even when nobody is around, you make a lane change without using a blinker that the car starts fighting to stay in the lane.'
Tesla owner Patrick O'Connor finds Lane Assist, part of the company's Autopilot system, frustrating. 'It is over-aggressive, and it doesn't seem to adjust well to naturally curvy roads. I have to turn my lane assist off because it keeps jerking me almost out of my lane—it thought I was swerving on the freeway, although I was following the road within the lane properly.' His wife, Ashley, drives a Kia and uses the vehicle's Smart Cruise Control regularly. 'As a mom of two children under five, I found it helpful in most insists when I drive the kids around. However, I do note that it needs more fine-tuning—it abruptly swerves and does not seem to have as much distance awareness as the system in my husband's Tesla.'
'We have a Cadillac Escalade, and I like the Adaptive Cruise Control because I can set it for 75 (even when freeway traffic is at 35), and it will stay with the flow of traffic automatically speeding up and slowing down. It's kind of nice,' explains Chad Armstrong. 'With that being said, the Reverse Automatic Braking tends to overreact sometimes by slamming violently on the brakes when there's nothing there. For some reason, and I know this sounds weird, it seems to be triggered by shadows.'
But not everyone is unsatisfied. Esther O'Connor, who drives a Subaru, appreciates the ADAS features. 'I love them. As you get older, I think they are great because they are very good at alerting you if you get momentarily distracted,' she said, referring to Subaru Lane Keep Assist, part of the company's standard EyeSight driver-assist system. 'Everyone occasionally gets distracted, whether while taking in road signs or watching for other traffic. The automatic system is good because it moves the steering wheel when you leave the lane, and it beeps.' But she's not smitten with all the systems. Esther has a steep driveway that continuously triggers Subaru's Reverse Automatic Braking (RAB) system when backing out of her driveway. When her Outback crosses over the gutter on the street, it automatically comes to a jarring stop. Frustrated, she's developed a work-a-round. She puts the transmission in neutral (thus defeating the ADAS) and rolls into the street without stopping.
Meighan Offield drives a Volvo equipped with the company's Pilot Assist & Adaptative Cruise Control System. 'I don't like using adaptive cruise control because I get disengaged from actually driving—same with the lane-centering self-steering. I need to keep my hands on the steering wheel for it to work anyhow, so I'd rather just steer and stay engaged,' she explains. 'Additionally, the adaptive cruise control brakes and accelerates too hard when cars change in and out of lanes in front of me. I prefer to be in control.'
Offield also notes other frustrations with ADAS, including one with Volvo's Rear Auto Brake (RAB) that mirrors Esther O'Connor's frustration. 'My driveway is sloped, so when I'm backing out of my driveway, the car senses the unlevel pavers and auto brakes. The system brakes really hard, and it's very startling—you think you have hit something. Fortunately, the button to disable it pops up on the screen when the rearview camera turns on, so I often disable it.'
Volvos are fitted with forward collision warning systems, which is part of the company's City Safety or Active Driver Assist features. 'When I'm driving on a curved road with parked cars along the sides, the forward collision prevention system kicks in and starts braking my car aggressively when it shouldn't,' Offield observes. 'It seems to read the parked cars on the side of the road, and because of the angle, it thinks I'm going to have a head-on collision. This is very frustrating, but unlike the back-up system, the forward collision system is not as easy to turn off without navigating to it in the infotainment system, so I leave it on.'
Charlie Schiavone drives a RAM 2500 pickup with Adaptive Cruise Control (ACC). 'I religiously use adaptive cruise control in every car I drive, including rentals when they have it. It takes away all the fatigue when driving, especially in traffic,' he explains. 'However, the sudden and harsh braking you get when a car gets in front of you is annoying. More times than not, there is enough space in front of you that simple coasting will suffice.' Schiavone also notes that the system doesn't drive naturally—like a human. 'When cars are moving out from in front of you, the adaptive cruise control accelerates way too quickly to close the gap, and if there is slowed or stopped traffic ahead, you need to intervene, or the system will do some harsh braking. It always feels like it engages too late—it feels like you're going to hit the car in front of you, and you may!'
Jeep owner Shannon McGee finds that ADAS offers some benefits but also has more than a few frustrations. Her vehicle is fitted with the company's Active Driving Assist (or Active Lane Management). 'Thankfully, my lane-keeping assist isn't as aggressive as other vehicles, and it just slowly corrects my wheel. However, my Jeep has a Forward Collision Warning with Active Braking, and the sensor isn't the greatest. My car will automatically brake if it senses another vehicle too close, and most of the time, there is no reason to brake—it brakes hard and beeps, too. It usually scares me more than helps me.' Like many motorists, McGee finds the system 'crying wolf' so often that it can't be trusted. 'I can see its benefits if I need it to prevent an accident, but it seems to activate when it's not needed, and it makes things more dangerous.'
Automakers have spent billions of dollars engineering, developing, validating, and testing Advanced Driver Assistance Systems (ADAS). However, studies and interviews indicate that most consumers still find them infuriating—to the point where they are ignored or defeated. The reality is that drivers prefer to maintain complete control of their vehicles rather than trust current ADAS technology.
Drivers I interviewed want ADAS technology to drive naturally and predictably, mimicking the way they drive—staying smoothly within the lane on the road, anticipating the flow of highway traffic, gently applying the accelerator and brake, and memorizing familiar challenges such as backing out of a driveway at home. They want ADAS to drive more like a human.
Despite widespread consumer frustration with current ADAS technology, the National Highway Traffic Safety Administration (NHTSA) is mandating that all new vehicles have emergency braking systems as standard equipment by September 2029. But unless automakers make drastic improvements to the technology, it appears that most drivers will simply shut it off.

This McLaren F1 Could Break Records. But Not For Speed
The McLaren F1, now 30 years old, is a well-established legend . Launched in 1992, examples sell today well into the millions of dollars. There's an F1 heading to auction next month that could go for $23 million or more when the hammer drops. The 1997 F1 in question, sold new to Oracle Software CEO Larry Ellison, has had three total owners and has accumulated less than 6,500 miles. Chassis 062 features several McLaren Special Operations upgrades, such as a sport exhaust (the original comes with the car), an upgraded air conditioning system, upgraded radiators, and an aluminum fuel tank. Photo by: RM Sotheby's Photo by: RM Sotheby's The car underwent a major service in October 2023, getting a rebuilt transmission, new spark plugs, and four new tires on the original magnesium wheels. It also got a new battery, a correct windshield , and some repairs made by McLaren Philadelphia to the gold foil that lines the engine bay surrounding the BMW-sourced 6.1-liter V-12. The McLaren , one of seven imported to the United States, wears Magnesium Silver with a black leather interior and a gray driver's seat insert. Ellison put only 2,600 miles on the car before selling it in 2005. The second owner sold it to its current owner in 2010, having driven it less than 1,000 miles. The car has lived its entire life in California, and that's where RM Sotheby's will auction it off next month during Monterey Car Week . If it sells for as much as the auction house values it at, it could become one of the most expensive F1s ever sold .

A Hefty Touring Bike With a Vintage Feel
Where I'm from in North Carolina, deer hunting was the easiest kind of hunting. Decades of game management had allowed the whitetails to overrun Croatan National Forest like rats with antlers. To make it more of a challenge, locals would sometimes hunt with primitive weapons—bow and arrow, single-shot handguns and even black-powder flintlocks, which stunk up the woods like spent fireworks. Our guest today, the 2025 Indian Chieftain PowerPlus Limited, is similarly motivated. If you've got a three-day weekend to kill, any number of high-tech, long-distance touring bikes from BMW, Honda or Ducati will put a round dead-center. All you have to do is pull the trigger.

As Tesla Gambles With Its Right to Sell EVs in California, How Should You Play TSLA Stock?
Tesla (TSLA) is no stranger to controversy, but the stakes may be higher than ever as the electric vehicle giant becomes entangled in a high-stakes legal showdown with the California Department of Motor Vehicles (DMV). At the center of the dispute are allegations that Tesla misled consumers by overstating the capabilities of its Autopilot and Full Self-Driving (FSD) technologies — claims that, if upheld, could result in the temporary suspension of the company's dealer license in California. This legal battle comes at a particularly vulnerable time for Tesla. Just a day ago, the company reported its steepest revenue decline in over a decade, and CEO Elon Musk warned of 'a few rough quarters' ahead. For investors already concerned about Tesla's weakening fundamentals, the prospect of regulatory penalties in a key market only adds to the uncertainty. More News from Barchart NVDA Broken Wing Butterfly Trade Targets A Profit Zone Between 150 and 160 Is Opendoor Stock a Buy at New 52-Week Highs? Can Lucid Motors Stock Hit $7 in 2025? Tired of missing midday reversals? The FREE Barchart Brief newsletter keeps you in the know. Sign up now! In light of all this, investors are left with a tough question: Should you hold, buy the dip, or head for the exits? Let's take a closer look. About Tesla Stock Tesla (TSLA) is a prominent innovator dedicated to accelerating the global transition to sustainable energy. The Elon Musk-led powerhouse designs, develops, manufactures, leases, and sells high-performance fully electric vehicles, solar energy generation systems, and energy storage products. It also offers maintenance, installation, operation, charging, insurance, financial, and various other services related to its products. In addition, the company is increasingly focusing on products and services centered around AI, robotics, and automation. Its market cap currently stands at $1.07 trillion. Shares of the EV maker have fallen 24.6% on a year-to-date basis. Tesla Sales Could Be Temporarily Suspended in California This week, Tesla faces off with the California Department of Motor Vehicles (DMV) over allegations that it overstated the capabilities of its Autopilot and Full Self-Driving technology, thereby misleading consumers. The stakes are high as the regulator aims to suspend Tesla's dealer license, which allows the company to sell vehicles in its biggest market in the U.S. The California DMV has been engaged in a years-long legal dispute with Tesla over how the automaker markets its 'Autopilot' and 'Full Self-Driving Capability' advanced driver assistance (ADAS) systems. The agency alleges that Tesla is misrepresenting the capabilities of its ADAS through both the naming of the systems and the way the company and its CEO promote them. More precisely, the California regulator asserts that Tesla violated state law by making 'untrue or misleading' statements in 2021 and 2022 while promoting its vehicles with advanced driver-assistance systems, including claims that the features were 'able to conduct short and long-distance trips with no action required in the driver's seat.' Meanwhile, Tesla has contended in legal filings that the statements in question are protected under the First Amendment of the U.S. Constitution as free speech. The company's lawyers also argue that the marketing statements cited by the DMV have been taken out of context and that the regulator is overlooking Tesla's warnings and disclosures regarding the systems. 'Tesla repeatedly and explicitly makes clear that its vehicles are not autonomous and require active driver supervision,' the company said in a February 2024 filing. Now, tensions are rising as the court holds a five-day hearing in Oakland on the case, which began on Monday and will run throughout the week. Notably, the hearing before an administrative agency judge coincides with an ongoing jury trial in Miami, where Tesla faces allegations that Autopilot was partially responsible for a 2019 crash involving a distracted Model S driver that resulted in a pedestrian's death. The DMV is now seeking a 30-day suspension of Tesla's dealer license in California. 'Tesla has been misleading consumers for years,' said Christopher Beatty, supervising deputy attorney general for California, who is representing the state's DMV, during his opening statement at an administrative court hearing in Oakland on Monday. Also, Melanie Rosario, a commander-sergeant with the DMV, testified in court Monday that Tesla's branding of its Autopilot and Full Self-Driving features was 'misleading' and 'contradictory,' stating that the terms suggest the vehicle is capable of driving itself. In Tesla's opening statement, the company's lawyers contended that it is 'impossible for a reasonable consumer to be misled' by the branding of its products, while also claiming that the company is 'getting closer every day' to delivering fully autonomous vehicles. If the DMV succeeds in temporarily suspending Tesla's right to sell vehicles in California, it could severely impact the company's performance this quarter. As noted earlier, California is Tesla's largest market in the U.S., accounting for roughly a third of the country's EV sales. What makes the situation even more ironic is that the looming end of the federal tax credit in Q4 is driving a surge in demand into the current quarter. And much of that demand was expected to come from California. Tesla Warns of Rough Patch Ahead Tesla released its Q2 earnings results yesterday after the market closed, and the stock is currently down 8% after the EV maker reported its biggest revenue decline in at least a decade. CEO Elon Musk also warned of tough times ahead for the company as incentives such as the EV tax credit phase out in the U.S. 'We probably could have a few rough quarters,' Musk said. Musk's remarks were his most direct yet regarding the impact of the tax bill signed by President Donald Trump this month on Tesla. Besides phasing out $7,500 tax credits for EV purchases, the law also dismantled federal fuel-economy standards that have been a significant source of revenue for Tesla over the years. Let's take a closer look at Tesla's Q2 figures. The company's total revenue slumped 11.8% year-over-year to $22.5 billion. Although the top-line figure was better than some feared, it still represented the company's worst revenue drop in more than a decade. The decline in total revenue was once again mainly driven by a downturn in Tesla's core automotive segment, which saw a 16% year-over-year revenue drop to $16.7 billion. Tesla attributed the decline to a 14% drop in vehicle deliveries during the second quarter and lower revenue from regulatory credit sales. Notably, revenue from regulatory compliance credits that Tesla sells to competing automakers dropped to $439 million in Q2, down 26% from the previous quarter and 51% year-over-year. As mentioned earlier, this revenue stream is at risk following the tax law signed by Trump this month, which removed the penalties automakers faced for not complying with federal fuel-economy standards. Another interesting thing I noticed is that automotive revenue fell at a faster pace than vehicle deliveries, indicating that average selling prices continued to drop amid intense competition. While the weakness in the automotive business was expected, the biggest surprise for me was the energy segment. The energy segment had always been a bright spot in the past, helping to partially offset the challenges faced by the automotive segment. However, this time Tesla's energy business posted a 7% year-over-year revenue decline to $2.8 billion in Q2, mainly due to a decrease in the average selling price of Megapack. I view this as a major negative for the company, as it seriously undermines my earlier bullish outlook on the energy business. Meanwhile, services revenue continued to perform well, rising 17% year-over-year to $3.05 billion. On the profitability front, the operating margin collapsed in Q2, dropping 219 basis points year-over-year to 4.1%, highlighting a clear erosion of competitive advantage. Tesla's adjusted EPS plunged 23% year-over-year to $0.40, but was in line with expectations. On the positive side, Musk said during the earnings call that production of a more affordable EV had started, with sales potentially beginning in the fourth quarter. The model, which Musk described as similar to the Model Y, is considered vital for boosting sales. As for the robotaxi, Tesla stated that it plans to improve and expand the service, which was launched this summer in Austin. The company is pursuing regulatory approval to launch in the San Francisco Bay Area, as well as in Nevada, Arizona, Florida, and several other places, according to Musk. 'We'll probably have autonomous ride-hailing in about half the population of the U.S. by the end of the year,' Musk said. 'That's at least our goal, subject to regulatory approvals.' What Do Analysts Expect For TSLA Stock? Wall Street analysts remain split on Tesla, with the stock currently carrying a consensus 'Hold' rating. While 12 analysts rate the stock as a 'Strong Buy' and two as a 'Moderate Buy,' 16 recommend holding, and 10 have issued a 'Strong Sell' rating. Notably, the stock currently trades above its average price target of $297.86. Analysts tracking the company foresee a 28.3% year-over-year drop in its adjusted EPS to $1.74 for fiscal 2025, while revenue is projected to fall 5.76% year-over-year to $92.07 billion. The Bottom Line on TSLA Stock I am deeply disappointed with Tesla's Q2 results, and more importantly, Musk indicated that the company would face even more challenges in the coming quarters. The revenue decline in the energy business nearly pushed me to issue a 'Sell' rating, but for now, I'm sticking with a 'Hold' to see how the launch of the new affordable model and the robotaxi expansion unfold. And let's not forget about the ongoing lawsuit with the California DMV. If Tesla's license is suspended this quarter, it would affect the company's sales during a very critical period and could also prompt additional regulations on how automakers market advanced driver-assistance systems. Therefore, I recommend keeping a close eye on the outcome here.
