This is just a database of normal driving. That's useful for learning how to follow the car in front and avoid stationary objects, but not much else. It's going to result in systems that drive like humans right up to the point they do something really bad.

A more useful database would be the one Nexar is accumulating.[1] They collect dashcam imagery of events where the driver did a hard brake or the system detected some other hazardous condition. That database could be used to train a system which recognizes trouble before braking starts.

Both systems need a much wider field of view. Probably at least 160 degrees, so cross traffic shows up before the collision.
