They have already been investigating Tesla’s automated driving systems for more than two years because of dozens of crashes that raised safety concerns.

The problems have led people who monitor autonomous vehicles to become more skeptical that Tesla’s automated system will ever be able to operate safely on a widespread scale. Stein says he doubts Tesla is even close to deploying a fleet of autonomous robotaxis by next year as Musk has predicted it will.

The latest incidents come at a pivotal time for Tesla. Musk has told investors it’s possible that Full Self-Driving will be able to operate more safely than human drivers by the end of this year, if not next year.

And in less than two months, the company is scheduled to unveil a vehicle built expressly to be a robotaxi. For Tesla to put robotaxis on the road, Musk has said the company
