Because you might still sit in a (slow going) car on a highway and high-speed crashes involving other (slower going) cars can still end deadly for the passengers on the slow car. Most highways in Germany already have a speed limit and setting limits for the few areas where it's not the case sounds like a good think for me as I had some quite negative experience with people going way to fast (for the amount of traffic). But I also feel that the 130cap is a bit low, while taking over cars I would like to be able to go a bit faster. Like ~145?? or so?
