Uber has paused self-driving operations in Phoenix, Pittsburgh, San Francisco and Toronto, which is a standard move, the company says.
The investigation is still active.
Uber began testing self-driving cars in Tempe in February 2017. The fleet of self-driving Volvos arrived in Arizona after they were banned from California roads over safety concerns. Gov. Doug Ducey touted Arizona as a testing ground, saying at the time in a written statement, “Arizona welcomes Uber self-driving cars with open arms and wide open roads.”
