In a blog post, Chris Urmson, the head of Google's self-driving car program, writes that the self-driving Google Lexus was stopped at an intersection near the company's Mountain View, Calif., headquarters on July 1. The light was green but the traffic congestion meant that the Google car, and the two in front of it, could not make it through the intersection without blocking it, he wrote. But the driver of a fourth car didn't notice the stopped traffic, only the green light, and plowed into the back of the Google car at 17 mph, without braking.

The Google car suffered only scrapes on its rear bumper. The car that hit the Google vehicle had its bumper fall off.

Haha.
