> But my personal view is that sacrificing safety so people can get from A to B a little faster is not worth it, and perhaps it's not clear whether or not speed is a big factor, but why risk it? Whats the rush?

It's not that simple that less speed equals more safety. Even the posted link shows no correlation.

Some people argue that speed in Germany is not risk, but a safety measure. German highways are already mostly overloaded with traffic. Decreasing the speed by introducing the artificial limits would effective make driving more dangerous because highways would be more crowded with drivers with less distance between, there would be more lane changing during driving, drivers will be more tired because of spending more time on the road. Also, driving at the uniform speed at the speed limit reduces awareness of the road conditions.

Another topic is that limit also works as a framing. On the road where limit is 120, everyone will tend to drive around 120, regardless of conditions. For the road without speed limit, people will generally drive 100 if that's optimal speed according to the current traffic conditions. And if it's safe to drive 180, why not?
