It is not the "speed" that kills, but the idiots who drive in the left lane below the speed limit, and the "racers" who pass on the right side.
In Germany, the Autobahn has fixed rules:
6. ....... If you can't walk half a mile, you should not drive.
Enjoy controlled chaos on the Autobahn.
Wish we did that here.
What does that have to do with the ability to drive a car well at high speed ?
