Key Facts

Waymo is trying out self-driving cars with a human "safety driver" on board Residents in a "dead-end" street in San Francisco say they are being plagued by an influx of self-driving vehicles.
Waymo says the vehicles are just "obeying road rules" designed to limit traffic in certain residential streets.
A spokesman for Waymo said the cars sometimes made a detour because of the presence nearby of one of San Francisco's "slow streets", which aim to limit traffic in certain residential areas.
In this case, cars travelling north of California on 15th Avenue have to take a u-turn due to the presence of 'slow streets' signage on Lake," the company said.
