Is it really good for society? Germany has the safest highways in the world. Also the only highways where it's exciting to see a police car while going 250 km/h.

Some try to dismiss this by saying that there are areas with lower speeds - yes; they're placed where you need to slow down anyway, it's more like "hey buddy, beware of this sharp curve" rather than "we will milk your wallet if you go 1 km/h over this idiotically low speed". I go to Berlin regularly (500km) and my speed average including the slowdown areas is around 230 km/h and I'm not even close to the fastest one on the road.

The best thing about this? The German diesel engine - drinking less fuel at these speeds than an American truck on idle.

Of course you can design a road to be safe at high speeds but normal roads aren't and normal people can't judge the safe speed.

I think that depends on the place. I can imagine that US cities with straight wide streets and roads are very hard to judge. But I can't imagine anyone having trouble with that in any European city... The top speed would be your last problem in any capital - you celebrate when it's not 0.

No, it motivates him to stop any driver that can't be confirmed to not be speeding under the level of 3d-party scrutiny the cop judges he risks to get under the circumstances.

And also the ones that are more likely to offer more money.
