However, Uber's self-driving car program has been mired incontroversy. Waymo, Alphabet Inc.'s autonomous driving businessthat is also testing driverless vehicles in Arizona, suedan Uber unit called Otto earlier this year for allegedly stealingdesigns for an important component of driverless cars known aslidar. Uber called the suit "baseless."

Prior crashes mostly minor

The photo, showing the Uber SUV on its side, suggests arelatively high-impact crash. That would be a contrast to theincidents involving self-driving cars tested by Waymo. In more than2 million miles of testing on public roads, Waymo's vehicles weremostly minor incidents, often when other cars drove into the backof their vehicles in busy areas.
