Driverless taxis are causing chaos at least in one major American city

A fully driverless taxi service called Cruise agreed to cut its fleet in half while officials investigate several crashes and strange behavior from the cars. The move comes a few weeks after regulators gave two companies the green light to run the robo taxis.

California's Public Utilities Commission approved the expansion of driverless taxi companies Waymo and Cruise to operate round-the-clock services in San Francisco. It was only a day later when several Cruise vehicles "created traffic chaos," according to Supervisor Aaron Peskin.
