A former Tesla manager who ran the company’s “Full Self-Driving” test fleet in Houston says the operation was so understaffed that its cars became “rolling hazards on public streets,” according to a lawsuit.

The manager, Javier Medrano, filed the wrongful-termination complaint in Houston federal court, and its contents were reported this week. He oversaw the fleet before Tesla launched its driverless “Robotaxi” in the city.

Elon Musk says Tesla expects to have self-driving working on the Tesla Semi “probably around the end of this year or early next year.”

Going by Tesla’s record on self-driving deadlines, it is: their jobs are safe for a long time.
