You don't really own the car though. You own steel and plastic and all that sure, they haven't figured out how to erode ownership of that yet. It's all worthless without software though and you don't get to own that. Now you are just licensing it. Now they can slap all the conditions they want on it. They fucked up and people died? Well enjoy your arbitration clause because that was a software issue. That dream of using your self driving car to make money, well you can do that on their network only with their rules.

Your would have to jailbreak your car to do that, of course…
