Tesla no longer sells cars with automatic driving capability. The hardware is there on newly shipping cars (although the sensor suite is weak) but it's not active. There's a lawsuit.[1]
It's unlikely that Tesla gets much useful data from vehicles. To debug a vision system, they'd need the camera data from all the cameras, and that's too big to upload over the cell phone data link.
