There's many ways to game our current system, too. You can just ghost-drive onto the highway in the wrong direction if you want to. What I mean is that I don't think every problem needs a technological solution - simple legislation and jail time should do it. EDIT: I agree it makes sense to have fail-safe systems, of course.

Yes but hacking the system allows you to remain physically safe and anonymous.
