This is like automatic speed enforcement: the current laws and limits are set up with the understanding that people break them, and that it's not really a big deal. If you want to change that so that they become unbreakable, all the benefit can't accrue to one side. There needs to be a rational compromise. In the case of speed limits, it means having adult ones like in europe. In this case it would mean making the car cheaper (which is obviously way more nebulous). I don't really see a first order problem, I'd pay more to have a car that doesnt allow third party control. The problem is when industry crowds out alternatives so we're all stuck with this, as we already are with all the over computerized crap that goes into cars
