Heh, heh, I know about the speed limits, but they are mostly dependant on photo-radar here, rather than patrols, and if you know where they are, no problem.
Anyway, I hit that speed on the Route du Soleil, the highway from Lyon to Marseille, at about 2 or 3 in the morning. France uses more mobile units than in Switzerland, and in hindsight I'm lucky I didn't land myself in jail.
That's also the same road I once took a Kawasaki ZZR 1100 to 250 or thereabouts (I wasn't about to let go of those handlebars to use a stopwatch!)
Generally, although the speed limit is 120, most drive at 130-140, and maybe 10% of people drive at 160 (100mph) or higher. Those speeds and the variances are OK in Europe because there is a high level of lane discipline. In the U.S., There are so many people who feel that the left lane is what you use if you are going a long way and don't want to get involved with incoming or offgoing traffic. If a cop in Switzerland ever saw a car pass another on the right on the highway, both cars will be ticketed - one for passing on the right, and the other for obstructing traffic (not letting faster traffic go by moving right).
The only thing you should feel when shooting a terrorist: Recoil.
