Lidar scanner

In between the two banks of cameras is the spinning Lidar array. Sixty-four lasers spin rapidly, scanning the buildings nearby, trees, the road, and even the road markings. More than 1.3 million data points are captured every minute as the True car rolls down the road. Unlike older street scanners, this car can capture at the posted speed limit. Nokia tells us that the company has been able to scan highways at up to 70 mph.
