This presumes that Tesla arrives at the software solution to autonomous driving before others. If Tesla is able to accomplish this, and Tesla's mission is to advance sustainable energy, doesn't it make sense for them to sell the capability to other car makers to use specifically for their EVs? They could choose to exclude licensing to ICE models. This would provide additional incentive to car makers to expedite their EV programs, and expand Tesla's reach and self-driving data faster than they could do on their own. Why would Tesla not license their capability?
