Tesla will give the National Highway Transportation Safety Administration (NHTSA) access to FSD Beta, according to a recent tweet from Elon Musk. Elon responded to a tweet from @WholeMarsBlog who pointed out that even the NHTSA was complaining about having to participate in the safety score process that all of Tesla’s FSD Beta testers have to do.
🤣 ok we’ll turn it on
— Elon Musk (@elonmusk) August 16, 2022
In the tweet, @WholeMarsBlog shared a screenshot of a letter from the agency to Tesla that read:
“As you know, NHTSA owns a Tesla vehicle with the FSD option.”
“With over 700 miles of driving this year and a Safety Score of 99 (including a score of 100 for the most recent 107 miles on January 21), we have not received the OTA update to fully enable FSD in our vehicle.”
“We request some of your time and expertise to asses our situation and help us understand what additional steps we might need to take.”
The letter was dated in January 2022 but is now being brought into the public spotlight on Twitter. This comes after some drama over the weekend. The CEO of Green Hills Software and founder of the Dawn Project, Dan O’Dowd, has been relentlessly campaigning against Tesla’s FSD Beta. The billionaire has recently published television ads claiming that Tesla’s FSD Beta is not stopping for children.
These claims have been debunked several times over the weekend and I wrote about two instances. In the first one, I interviewed @TeslaDriver2022 who performed a test with child-sized Amazon boxes.
“The FSD Beta has just been getting better exponentially even since I’ve been using it. Just some of the predictions it’s got and the capabilities to understand when things are getting in their path. Not even that. Some of the most impressive stuff is just when I’m driving down the road at 45 miles an hour and there’s a car that will turn in front of me to get into a parking lot.
“Its ability to understand whether or not that car is gonna make it or not and whether or not it needs to slow down. It’s becoming very human-like.”
In the second article, @WholeMarsBlog tested FSD Beta on a child-sized mannequin and allowed Tad Park to test it on his son. In each test, FSD Beta recognized and stopped for pedestrians. He told me that the test showed that FSD Beta has no problem detecting pedestrians of all ages.
However, critics claim that the Tesla owners are vile for testing it on their children, yet are refusing to acknowledge that O’Dowd’s claims were disproven. The idea of testing such software on a child may seem horrifying to those who don’t understand the software or know how to drive.
A father who loves his child would quickly take over and brake if the software were to refuse to stop. And in the video, you can see clearly see the screen recognizing the child and stopping at a very safe distance.
In O’Dowd’s videos, the screen is hard to see and you can see some type of error message as the driver refuses to disengage. Many in the Tesla community have pointed out that the driver was accelerating. If this is the case, then FSD Beta would have to allow the driver to take over. This includes acceleration.
Aka, something like "Accelerator pedal is pressed – car will not brake" or "Front camera blocked or blinded".
Why do you keep driving with errors? Why do you keep "coincidentally" posting videos with them too blurry to read?
People have been asking you this from Day 1, Dan.

With Tesla granting the NHTSA access to FSD Beta, the agency will most likely do testing of its own. This, I think would be a very good thing considering that the agency and its employees aren’t running for political office for the sole reason of taking down Elon Musk.
The agency and Tesla may have gone head to head a few times, however, safety is important for both Tesla and the NHTSA so it makes sense to grant the agency FSD Beta for its vehicle.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
