Those Tesla cars aren't collecting training data, that's preposterous. They have a mobile phone connection and some flash storage, so where is all this data going to? It's not going over the mobile link, you would need many magnitudes the bandwidth, and it's certainly not going on the flash storage, because if you continuously stream raw camera data to flash you will kill it in a year at most. (That is before you consider that you want a $100k sensor suite with lidar, precise wheel odometry and a GPS/INS system to get a ground truth for training anything)
