In Germany the police travel in the fast lane and use this LED arrow type thing to tell the slow pokes to move out of the way.

That being said, way too many drivers travel TOO fast in the left lane around here. If someone makes a blinders switch into the passing lane and the oncoming SUV is doing 80+ mph (in a 55) that SUV is going to lay into the brakes, or weave into the middle lane. I think people forget the difference between a passing lane and a go as fast you want lane. There's no autobahn here and there's a speed limit for a reason -- the cops generally will only spot you 10 mph over it. 20+ mph over the limit and you are well on your way to creating a dangerous condition. Sure some drivers are experienced but my anecdotal experience is that the more experience a driver is in the area of crash avoidance skills, the less likely they are to be driving that fast in the first place. An experienced driver gives himself a buffer in all directions. Speeding in the passing lane means you only have one escape, moving to the right and that's if there's a gap when you need it.

Personally I think the guy doing 30+ mph over the limit in the fast lane is more dangerous than the slow poke creating all the weaving. At least the weaving is happening at expected speeds.
