Self-drive cars ‘still need human help’ according to California reports

Futuristic self-driving cars travelling along California roads have needed human intervention to stay safe, according to test reports.

California’s Department of Motor Vehicles (DMV) released reports filed by seven companies given permission to test prototype vehicles in public which gave instances in which a driver had to take over because of technology problems or other safety concerns.

Experts in the technology said Google, whose cars drove the most by far, performed relatively well, but also cautioned that testing typically happened during good weather.
