General Motors has more than doubled its Californian self-driving car fleet in the last three months, the US motor giant said overnight.
During testing in the last month, all incidents or crashes were the result of third parties – human-operated cars or bicycles – rather than GM’s autonomous fleet, a spokesperson confirmed.
The number of robot-driven cars on the streets of California jumped from between 30 and 40 to 100 over the last three months.
Investors have been buoyed by GM’s progress reports, with shares in the US-listed firm up nearly a fifth in the last month.
Yesterday, a US Senate panel approved legislation allowing for the expansion of testing of self-driving cars.
Californian law stipulates all incidents involving autonomous vehicles, regardless of severity, must be reported.
None of the reported incidents resulted in injuries or serious damage. GM has reported 13 incidents relating to driverless cars in 2017. This compares with three crashes reported by Google’s Waymo project.
