And not much lidar data, right? I don't work on this, but I imagine the quality of the data set makes a big difference. From what I've learned, lidar and radar are typically used for object detection (i.e., avoiding other cars; perhaps augmented with camera data), while cameras are used for things like lane detection and traffic sign detection. If Tesla is trying to solve the same hard problems as everyone else, using weaker equipment, I wouldn't bet on them having a lot of success. Also, kind of the point of this article is that Waymo has a test area where they can get real data along with the ground truth. That seems much more valuable than unlabeled/random data.
