A Tesla Model Y equipped only with the automaker’s eight external cameras, and no radar underwent an extreme Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB) stress test, thanks to owner Kevin Smith.

Smith, who has a new 2021 “Tesla Vision” Model Y without any radar hardware, wanted to assess the all-electric crossover’s ability to recognize and avert obstacles on a closed course. Smith said this was the second round of testing, and he used an inflatable clown as the obstacle that his vehicle would have to avoid to consider the test a successful one.

In May, Tesla announced that it would be removing radar from Model 3 and Model Y vehicles that were manufactured in May 2021 and beyond. In an attempt to transition to a camera-based approach for its cars, a plan that Tesla set out many months ago, the automaker chose its two mass-market vehicles as the guinea pigs to accumulate data for future use. The Model S and Model X are keeping radar, but only for a short time. Eventually, both Tesla flagship vehicles will also transition to Tesla Vision.

For now, the Model Y and Model 3 are the only two vehicles that will not utilize any radar hardware for the foreseeable future. Many owners who have utilized Tesla’s Autopilot of Full Self-Driving suites for semi-autonomous driving capabilities grew concerned when the automaker announced it would be ridding vehicles of any radar, with the most common complaint being performance in severe or low-visibility weather. Instead, Tesla believes that a vision-based approach will actually make the vehicle’s performance much more robust and accurate, comparing the vision-driven system to that of a human driver.

CEO Elon Musk commented on it during the Q1 2021 Earnings Call:

“…when your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”

In Smith’s stress test, it proves that Tesla’s camera-based approach definitely needed some work early on. As a result, Tesla launched Software Update 2021.4.18.1, improving the performance of Autopilot for Vision-based automobiles. The vehicle successfully stopped while operating on Autopilot based on multiple test runs with the inflatable barrier. However, the manual test, where Smith controlled the car and depended on FCW and AEB to stop the car automatically, wasn’t as successful. All manual runs activated FCW, but AEB only interfered a handful of times. The vehicle didn’t stop, either. It only slowed down, softening the blow and unfortunately deflating Smith’s blow-up clowns.

Other owners have indicated that Autopilot’s performance with Tesla Vision has led to more confident showings of Autopilot compared to other vehicles that equip both cameras and radar. Tesla also added several safety features and new additions to vision-only vehicles. Teslas will only become more confident as the Neural Net compiles more data from Tesla Vision cars as they become more popular in the coming months.

Tesla makes latest announcement on Model S and Model X

The announcement follows Tesla CEO Elon Musk’s statement on the Q4 2025 earnings call in late January. Musk described the decision as an “honorable discharge” for the two vehicles, noting that production would wind down in Q2 2026.

Tesla has officially begun winding down production of its flagship Model S and Model X in the United States, notifying owners via email that the long-running models will soon reach the end of the line.

The email, sent to U.S. customers on March 27, opens with gratitude. “Model S and Model X marked the beginning of the world’s transition to electric transportation,” it reads. “These vehicles also made it possible for Tesla to develop the technology that would move our world toward autonomy.”

It then delivers the news directly: “As we make way for this autonomous future, Model S and Model X production will be ending. If you’d like to bring home a new Model S or Model X, order yours soon from our limited inventory.”

The message closes with a simple thank-you: “Thank you for being part of our journey.”

The announcement follows Tesla CEO Elon Musk’s statement on the Q4 2025 earnings call in late January. Musk described the decision as an “honorable discharge” for the two vehicles, noting that production would wind down in Q2 2026.

The move frees factory floor space at Fremont, California, for next-generation manufacturing, including Optimus humanoid robots and the upcoming Robotaxi platform.

Introduced in 2012 and 2015, respectively, the Model S and Model X were Tesla’s original halo cars. They proved EVs could outperform gasoline luxury vehicles in acceleration, range, and tech features while pioneering over-the-air updates and early autonomy hardware.

Although they never matched the volume of the Model 3 and Model Y, their engineering breakthroughs laid the foundation for the company’s current lineup and full self-driving development.

Early adopters highlighted how the cars convinced them to invest in Tesla stock and the EV movement. Some U.S. owners who had not yet received the note voiced mild frustration, and international customers confirmed the outreach remains U.S.-only for now.

Tesla has not detailed an exact final production date beyond the Q2 2026 target or confirmed immediate replacements. Speculation continues about a possible Cybertruck-derived SUV, but the company’s public focus has shifted squarely to autonomy and robotics.

For buyers still interested in the S or X, the window is closing. Inventory is described as limited, and Tesla’s Korean division has already set a March 31 cutoff for new orders in that market. The email serves as both a farewell and final sales push, an elegant close to a chapter that helped define modern electric driving.

Tesla drives drunk owner while he naps, Police still arrest him on DUI

A Vacaville man let his Tesla drive while he napped, but police had other ideas.

A Northern California man found a creative solution to drunk driving this week by letting his Tesla drive him around while he took a booze snooze. Police in Vacaville arrested a man on a DUI charge after he was found, what appears to be, completely passed out behind the wheel of a Tesla Model Y, which was safely self-navigating the owner through busy streets. The man’s passenger seat told the rest of the story, with a four-pack of Sutter Home wine bottles and a box of Round Table pizza clearly visible.

According to the Vacaville Police Department, as posted through their Facebook page, a concerned community member spotted the very relaxed driver, stayed on the line with dispatch, and guided officers to the intersection of Elmira Road and Shasta Drive where they stopped the vehicle. Alcohol and marijuana were confirmed. No medical emergency, and what appears to be just an extremely committed drunken nap.

The Vacaville Police noted that California permits drivers to use assistive driving features like Tesla’s FSD, but the law still requires them to be “conscious, alert, and not under the influence while operating them.” The post drew some humorous reactions in the comments section, with one commenter piping in, “That time when his vehicle had more situational awareness than he did.” Another commenter chimed in, “Sutter all the way home….”

The incident lands in an interesting moment for Tesla. Elon Musk caused his own stir in December 2025 when he responded to a user question about whether FSD v14.2.1 allowed texting behind the wheel with a simple “Depending on context of surrounding traffic, yes.” He had earlier told investors that drivers turning off autopilot to check texts while steering with their knees was “significantly less safe” than simply letting FSD run, which he called “kind of the killer app.” Neither statement included anything about Sutter Home wine being part of the equation.

Tesla’s all-electric Semi is proving more than just a flashy concept as it is winning converts among the professionals who know trucks best.

As fleets roll out Pilot Programs for Tesla across North America, drivers are raving about the Class 8 electric truck’s unique features, including a centered driver’s seat, massive touchscreen visibility, instant torque, and absence of gear-shifting fatigue.

These features are transforming long days behind the wheel into noticeably easier, less stressful shifts.

In a recent Wall Street Journal profile of early pilots, Dakota Shearer of IMC Logistics described backing out of a tight spot he had mistakenly entered:

“I backed right out of there, no problem. It’s like I’d never done it in the first place. That right there showed me that the technology the Tesla has makes a big difference.”

His colleague Angel Rodriguez of Hight Logistics, who switched from a 13-speed diesel, agreed:

“It’s just easier on your body. It’s less stressful because you’re not really having to engage the clutch and the stick shift.”

Veteran drivers in other tests echo the same enthusiasm. Tom Sterba, a Senior Driver at Saia, spent days testing the Semi and came away impressed with the navigation and overall feel:

“The navigation systems in these trucks are just unbelievable. That’s what I love about it.”

Sterba summed up the experience with a line that has since gone viral among trucking circles:

“I hope I retire in this truck.”

Pilot programs with ArcBest, thyssenkrupp Supply Chain Services, and Mone Transport delivered similar feedback. Drivers consistently praised the center-seat layout for eliminating blind spots, the smooth acceleration, and the overall comfort and safety.

Real-world data backed the hype, as ArcBest logged thousands of miles at efficient consumption rates, even over the challenging routes, like Donner Pass, while other fleets beat Tesla’s own efficiency targets.

The consensus among participants is clear: the Semi feels quieter, quicker, and far less physically demanding than diesel rigs while delivering three times the power and dramatically lower operating costs.

The latest chapter in the Semi’s story arrived just days ago on Jay Leno’s Garage, as Leno became the first outsider to drive the updated long-range production model, joined by Tesla Chief Designer Franz von Holzhausen, and Semi Program Director Dan Priestley.

Tesla reveals various improvements to the Semi in new piece with Jay Leno

The episode revealed major upgrades heading to volume production this year: the truck sheds roughly 1,000 pounds, adopts a 48-volt architecture, switches to fully electric steering with Cybertruck-derived actuators, and uses 4680 battery cells engineered for an over-one-million-mile lifespan.

Aerodynamics improved, enabling a 500-mile range on the long-haul version, and about 325 miles on the shorter-wheelbase standard-range model. Megachargers can now deliver up to 1.2 megawatts, adding roughly 300 miles in about 30 minutes.

Leno hauled heavy loads and marveled at the turning radius and effortless power delivery. “I don’t feel like I’m pulling anything,” he said during the episode.
