> Google has been working on this problem for longer and they have access to the largest image/video datasets in the world to train their models
As of August, Google's self-driving cars have 2 million miles of real on-road experience, while Tesla's Autopilot systems have 140 million. They're beaming back data to Tesla the whole time.
My understanding is because Tesla has to send their data over the cell network it is first heavily processed/reduced by the cars onboard computer before being sent back (in order to conserve bandwidth). So I am not sure if it's fair to compare the 2 company's datasets based on miles driven alone.
