What about the idea that, as a customer who bought and owns something, you should have control over that thing, not the other way around? I am not saying this is the stronger argument. It's still an argument, though, and it surprised me to find this sentiment missing from the comments (granted, we're at only 7 comments right now). Why would something we want applied to smartphones and PCs not apply to cars?
… because it’s really hard for me to misuse my smartphone to the point where it kills someone/myself.
For Apple iPhone, for example, you just have to assert that you aren't driving to use it while driving (assuming the iPhone could be used by a passenger instead, so they can't really tell).
