Uber blames humans for self-driving car traffic offenses as California orders halt

Regulators ordered Uber to take self-driving cars off roads in San Francisco and company suspends drivers after vehicles were caught running red lights

California regulators ordered Uber to remove its self-driving vehicles from the road on the same day that the company's vehicles were caught running red lights - violations the company immediately blamed on "human error".

"It is essential that Uber takes appropriate measures to ensure safety of the public," the California department of motor vehicles (DMV) wrote to Uber on Wednesday after it defied government officials and began piloting the cars in San Francisco without permits. "If Uber does not confirm immediately that it will stop its launch and seek a testing permit, DMV will initiate legal action."
