Uber is putting its self-driving car tech tests on hold after one of its cartage was complex in an blow in Tempe, Arizona over the weekend. The adventure was spotted and photographed by Fresco News user Mark Beach.

One of Uber’s self-driving Volvo SUVs was found on its side after it collided with addition agent while in free mode. According to Tempe police who spoke to Bloomberg, the company’s car wasn’t at fault; a second car failed to yield for the Uber and caused it to flip over.

The aggregation says that there were no austere injuries and that the SUV didn’t have any backseat passengers.

While the police report indicates that Uber’s agent may not have been at fault, it’s worth noting that it could well have had a noncombatant commuter in the back, as the company’s trials allow some users to ride in its self-driving cabs when they hail an UberX. And as TechCrunch notes, the fact that the agent had tipped over on its side could mean that it was traveling at an unnecessarily high speed.

Uber first began testing its self-driving cabs in Pittsburgh in August 2016, and launched trials in Tempe in February after it was arrive to do so by Arizona Governor Doug Ducey.

One of the company’s free cartage ahead ran a red light; Uber claimed this was due to human error, but that has since been refuted by The New York Times.

The aggregation is also being sued by Waymo, a self-driving tech firm owned by Google’s parent aggregation Alphabet, for allegedly burglary a key basic of its proprietary free aeronautics technology.

It isn’t yet clear how soon Uber will be able to bounce back from this one. A agent said it’s attractive into the adventure at present; amid that and the Waymo lawsuit, it may well be a while before we see addition Uber test agent on the streets.
