Uber self-driving cars were involved in an accident 37 times in the eighteen months before the fatal accident with a pedestrian in March last year. That said the US road safety authority National Transportation Safety Board Tuesday, Reuters writes.
In 33 cases, other vehicles crashed into a test car. This included a case where a curved pole blocked the road in front of the car and a situation where the driver took over the wheel to avoid a ghost driver. The driver then drove a parked car.
The non-fatal accidents occurred between September 2016 and March 2018. In March 2018, a test car hit a pedestrian in the US state of Arizona after the car had applied the brakes too late. Uber would have previously set off an emergency braking system in the car.
The crash in Arizona was the first fatal accident with a self-driving car. Uber then stopped testing the self-driving cars, but resumed it again in December last year with improved emergency procedures and safety systems.
The US road safety authority is currently investigating the crash.
