One of the goals of Tesla Inc TSLA and its CEO Elon Musk is a transition to fully autonomous driving. Musk believes FSD leads to fewer accidents and fewer vehicles like a Tesla Model 3 could be totally damaged.

What happened: A Tesla Model 3 was rolled over and crushed backwards by a school bus in a video that was widely viewed online.

The video was shared by Wham Baam Teslacam on YouTube, an account with over 450,000 subscribers. The video shows the bus climbing over the front end of a Model 3 that failed to swerve.

The owner of the Tesla was standing behind a school bus at a stop sign. The school bus driver didn’t see the vehicle behind him, which might have been a little too close. The bus driver realized they weren’t in the right lane to make a left turn and reversed, according to the report.

The school bus backed onto the trunk of the Tesla, smashing the front end of the car and the windshield.

Why it matters: No one was injured in the accident and the video could serve as a lesson for drivers to leave space behind school buses and buses to ensure there is no one behind them when reversing.

The owner of the Tesla Model 3 has ordered a Tesla Model S Plaid to replace the totally damaged vehicle.

Musk is optimistic about the future autonomous vehicles. “Self-driving sounds like magical fiction until you actually use it,” Musk said in an interview with the Tesla Owners Silicon Valley Club earlier this year, comparing FSD to a unicorn.

The Tesla CEO said self-driving had significantly fewer accidents than traditional driving and companies like Tesla shouldn’t be penalized for the accidents that do happen.
