Mark Rosekind, the former head of the U.S. National Highway Traffic Safety Administration, has joined Zoox, a secretive Silicon Valley startup building a fully self-driving car, according to Reuters. He will be its chief safety innovation officer.

Zoox, which has raised more than $200 million in funding, will undoubtedly benefit from having Rosekind’s expertise in transportation regulation given its lofty ambition of rolling out self-driving cars that won’t even require passengers to pay attention.
