A well-known Tesla hacker has released his thoughts about the recent claims of “Sudden Unintended Acceleration,” claiming that the company’s vehicles are not capable of gaining speed on their own.
Self-proclaimed “Tesla Tinkerer” Jason Hughes has been vocal about the company’s hardware issues in the past. Hughes has managed to make something of a career of recognizing flaws in Tesla vehicles and addressing ways to fix them. However, Hughes is not a believer in the new claims that Teslas will subject some owners to unexpected acceleration and has now publically dispelled them.
Hughes took to his Twitter account to address the rumors and claims they are simply an attempt to blame Tesla for mistakes the driver may have made, or an attempt to gain attention through the internet and gain traffic to a website. Hughes stated, “Seriously, Teslas do NOT have a sudden unintended acceleration issue. The engineering here is spot on. They have people not wanting to accept responsibility for their screw ups, plus clickbait.”
So the BS sudden unintended acceleration claims are front and center again… *sigh*

While Hughes states that he does not hold any TSLA stock, he is a supporter of the company. In the past, Hughes recognized issues with the MCUv1 hardware and brought them to light for Tesla owners to ponder. While he claims to have issues with some of the things Tesla has done with their vehicles, he fails to believe the company has issues with something that is as simple as a gas pedal.
In a post addressing the issues on the Tesla Motors Club forum, Hughes said, “Tesla’s accelerator pedal is actually the exact same drive-by-wire pedal used in several other manufacturer’s vehicles. It’s a highly proven technology over decades. Nothing special at this point. No Tesla secret sauce here. Just two hall effect sensors with slightly different curves for redundancy and position validation. If they don’t agree, the car doesn’t move.”
Hughes believes that any issues with sudden acceleration may be the fault of the driver. “I’ve almost made a pedal misapplication mistake several times in the past with multiple different vehicles… fortunately not in any catastrophic situation. We’re not infallible creatures. You get in a zone of habit, feel like you know what’s going on, and when something unexpected happens you’ll swear you were doing everything normally the way you’ve done it 10000 times before, when in reality you just screwed up. It happens,” he added on the TMC forum under his username wk057.
Tesla released an official statement on the Sudden Acceleration claims on Monday, January 20, and claimed they were completely false. Tesla has worked closely with the NHTSA to resolve any issues that come forward with its cars and all research and data have shown that the company’s vehicles accelerate in a proper fashion.
Hughes’ belief that Tesla’s vehicles are not capable of sudden acceleration is more credible than most claims. Hughes has spent years breaking down and finding issues with Teslas, but he simply finds no proof in the claim that the vehicles are randomly accelerating. “But in this case, Tesla did their homework on the hardware and software side very well to make sure this would never be an issue. Kudos where due,” he said.
Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.
However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

• Six-seat long-wheelbase Y. Shanghai. On sale since August 2025
• Owners say the rear tire-to-arch gap shrinks after mileage or a full load. Some cases after about 9,000 km loaded. Others near 30,000 km

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.
Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.
Tesla Model Y L is gaining momentum in China’s premium segment
Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.
There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.
Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.
