State of the art, aye, but definitely funny hearing about the job I was at 7 years ago (where things were fully operational, not experimental) being referred to as so new! When I was there, it was a combination of (1) downwards facing line lasers measuring distance + reflectivity, (which was viewed as a greyscale image, around 4k pixels == width of a lane iirc) and (2) forward facing cameras for tagging assets like signs, plus (3) velodyne lidars for much coarser 3D point cloud (including measuring bridge heights). The scanning worked up to a bit under 70 mph, which was impressive to me, particularly that first part of the sensor package.
