Drunk driving already has very harsh penalties. Excessive speeds tend to have very harsh penalties too depending on the state. There's absolutely no point to a limiting system (in these contexts) that has a user override. The people doing these things have already made the conscious choice to do them.
That's not at all in their comment. Their comment even says if they get caught with the override on.
Filing a report would be interesting, although I'm not sure feasible it would be to track and intercept every vehicle filing a report. Not to mention, the habitual offenders will just use old cars without the tech, or bypass it.
Even at 150mph in a residential zone? That was the sort of speeding being discussed.
Yes, minor speeding here in the US is similar. Many states will arrest you and impound your vehicle if you do 26mph (or 31, etc) over the limit or exceed some predetermined spped like 99mph. Similar if you are found to be racing, or performing any action the police see as "reckless endangerment" (including of oneself and nobody else).
