Electric Engineer Tracy Xu took these picture of a Lincoln sedan driving on highway 237 in Mountain View, California on November 30th, 2016. The car is operated by Chinese internet behemoth Baidu and shows several sensor systems mounted on the car.
On the roof is a spinning LIDAR, with what appears to be two solid state LIDARs additionally one the side. On the back bumper there is a black rack to which two black boxes are attached, which probably are radars. There is another one dangling on the side behind the tire. The same configuration seems to be used at the front of the car.
Baidu is one of 19 companies that currently have received a license to test autonomous vehicles on public roads in California.
