I remember after market versions of this in the 90s. To start the car, you had to blow. No communication and nothing more complicated than it. It seems crazy to me that we still haven't required this. We also should have lowered the legal blood alcohol limit ages ago!

I also think we should require governors to limit acceleration and top speed. Since cars have had GPS for 15+ years, this could be dynamic, so no doing 55mph down at 20mph residential street!

I suppose, by the time we actually implement this, it'll be moot, as we are getting closer and closer to automated cars.
