Here is my statement regarding the tragic event that occurred in Tempe overnight.
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.”
One of the self-driving cars was involved in a crash a month later , after a car failed to yield to the Uber vehicle and hit it, authorities said. The self-driving SUV rolled onto its side as a result crash.
There were no serious injuries reported in that crash.
