In Europe, the Heavy Equipment drivers (i.e. Tractor Trailer, Dump Truck, Bus, etc) Are regulated by the time between toll booths. BIG fines if they are even so much as a minute too soon. They have to drive the speed limit.
And DUI is loss of license for life no questions asked, do not pass go, do not collect $200.
The up side? The autobahn.
It's safer in my opinion, and it allows those with high performance vehicles to drive them in well controlled conditions. You don't see poeple driving 60mph in the far left lane. What you do see is all the trucks staying to the right, all the slower drivers staying to the right, and the left lane moving along at 100.
They also take driving much more seriously. People are trained to drive and it's thought of as more of a privilage than a right.
Over there, people are responsible for thier actions behind the wheel. Over here, "it's never my fault". And that's what makes those of us who know how to drive have to put up with doing 65mph on a newly paved, perfectly straight, 4 lane freeway.
I'll take their system over ours any day.
