A Tesla bought today does have the hardware to implement what they call full self driving, once the software is ready and state regulations, if any, are in place. That being said, i would imagine said hardware would evolve over time with new releases. It would be nice, and probably safer, if cars could actually communicate with each other, rather than have to rely on their own cameras, to determine another vehicles position. Same with traffic lights, road signs, etc. that's probably a long way off, although i wonder if Teslas have hardware that would allow them to communicate with one another.

> if cars could actually communicate with each other, rather than have to rely on their own cameras, to determine another vehicles position. I wonder how useful it would actually be though. I don't think you'd want to involve such a complex a distributed system in a hard-realtime domain like deciding whether you're about to hit the other vehicle, the CAP theorem seems pretty unavoidable there.

  Probably also not the best to actually trust the data from other sources without verifying it yourself anyhow.

  Just think of a few common cases. Sending out a "applying emergency brakes at coords x,y"... You maybe don't drive in a ditch to respond but maybe your AI starts the braking process as it evaluates...
