A Tesla owner recently shared a theory on factors that might have led up to the fatal Model X accident near Mountain View, CA, on March 23. Driving on the same stretch of road on Autopilot, the Tesla owner observed that there were deviations on the street’s markings and repair cuts — things which might have caused the electric car’s sensors to misread the highway’s lanes.
The 36-second clip was uploaded and shared on YouTube by Privater, who included annotations to the video highlighting his observations. At the 0:05-second mark on the clip, the Tesla owner noted that the markings on the road deviated from their original line due to the beginning of a repair cut. Further into the street (0:12 into the clip), Privater noted that the repair cuts in the road became very prominent. This could have confused Autopilot into thinking that it was a lane, especially under the direct glare of the sun.
As the barrier where the fatal Model X accident took place in came into view (0:23 into the video), Privater noted that the section of the road leading up to the crash cushion was marked by solid white lines. As could be seen in the Tesla owner’s clip, the lines were almost wide enough to be a lane, which could have also been misread by Autopilot.
The Tesla owner noted that he had been driving on the same stretch of road on Autopilot for almost two years. During that time, Privater stated that his car had misread the road marks and nearly collided with the crash cushion once or twice. He described his experiences as a response to a comment on his YouTube video.

“On the video, my car is on Autopilot. I drive the same section for nearly two years, (and) 99.9% of (the) time, I’m on Autopilot. However, this kind of error only happened to me once or twice. It’s scary enough for me to keep high alert on this intersection,” he wrote.
In an update to its first statement about the fatal Model X accident, Tesla confirmed that the ill-fated electric SUV was on Autopilot when it collided with the highway barrier. According to Tesla, the Model X driver had received several visual warnings and one audible hands-on warning earlier during the drive. The ill-fated electric SUV’s driver had also not placed his hands on the steering wheel for 6 seconds before the fatal accident. Overall, the Model X driver had about 5 seconds and 150 meters of unobstructed view to steer the car away from the highway divider before the collision occurred.
In a statement to Reuters, NTSB spokesman Chris O’Neil expressed the agency’s disagreement about the Elon Musk-led company’s decision to release information about the investigation to the public.
“The agency needs the cooperation of Tesla to decode the data the vehicle recorded. In each of our investigations involving a Tesla vehicle, Tesla has been extremely cooperative on assisting with the vehicle data. However, the NTSB is unhappy with the release of investigative information by Tesla,” O’Neil said.
As we noted in a previous report, the Model X crash was so severe because a crash attenuator, a highway safety device designed to absorb the impact of a colliding vehicle, had not been repaired by CalTrans since a 2010 Toyota Prius smashed into the safety device 11 days before the Tesla accident. In a statement to ABC7 News, Caltrans stated that the standard timeline for a crash attenuator’s repair is 7 days or 5 business days after an accident. The safety device’s repairs were delayed, however, due to storms in the area.

Tesla adds new feature that will be great for crowded parking situations
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.
Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.
Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:
The nice little touch that Tesla have put in the app – continuous tracking of your vehicle location relative to you.
There’s people reporting dizziness testing this.
To those I say… try spinning your phone instead. 😉 pic.twitter.com/BAYmJ3mzzD

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.
However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.
It also reveals the distance you are from your car, which is a big plus.
Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.
Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”
Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.
Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.
While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.
Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.
The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”
This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.
Jeff Dean, the Chief Scientist for Google DeepMind, said on X:
“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”
Musk replied:
“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”
Waymo never really had a chance against Tesla. This will be obvious in hindsight.

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla AI5 project begins to move forward
According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team.
Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.
According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.
The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.
The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.
Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.
The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.
Tesla teases new AI5 chip that will revolutionize self-driving
AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.
Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.
“We’re going to focus TSMC and Samsung, initially, on AI5. The AI5 chip, design by Tesla, it’s an amazing design. I’ve spent almost every weekend for the last few months with the chip team working on AI5.”
It will be 40x better than the AI4 chip, Musk says.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
