What does that data give you? Raw sensor data + steering angle + acceleration/braking is not particularly useful in of itself. Nobody is trying to shove large amounts of data through a blackbox model and directly trying to predict car controls from images. This is not MobileEye's approach and almost certainly isn't Tesla's approach. The bottleneck is data that is decomposed and labeled in greater detail (lane markings, obstacles, bicyclist hand signs, etc) - and you need human annotators for that.
