I live in Germany, and routinely drive faster than that. With good roads and reasonably trained drivers this isn't an issue
The faster you drive the more stress you produce in other drivers. The faster you drive, the higher the risk.
And i have seen plenty of ' trained drivers' thinking its reasonable to start taking over on the right side because 2 cars are ahead of him. swiffling into your lane without proper safetydistance, starting to take over everyone from the 3th or 5 position...
If you don't drive faster than 180 at night on an empty autobahn, you just might be a dick and ignorant to everyone else you share the autobahn with. And yes when i do this, it might be a short sectionwere it is very clear that its for fun and thats it.
