Great. Point me to the next closest open source/hardware car that's not a jalopy, is road-worthy and crash-safe, is globally available, and that doesn't cost 2x the retail price of a "consumer" car.
The point isn't that a particular closed source car is available, but that there are always a few locally-available models that do the basic things well no matter where you are in the world. With open source cars, this is unlikely.
No one said it would be easy, but offering a software suite to a hardware company shouldn't be too hard of a sell. Not like any of them really want to make software.
