US car manufacturers reported nearly 400 crashes involving cars with partially autonomous driver assistance systems, according to a new report from a US car-safety regulator released on Wednesday.
Tesla, which has about 830,000 vehicles on the road with driver-assist programmes that have partial control over speed and steering, reported 273 crashes, about 70 percent of the total, according to The Associated Press. Companies caution that drivers must remain prepared to intervene and take control of driving at all times, even in cars with partially autonomous systems.
