For reasonable people yes, but those that go 30km/h over the speed limit every time don’t care and will always drive as fast as possible in those sections. I once met a guy who claimed to know down to the exact last km/h how fast he could drive until the car lost control in every single curve of a quite curvy road segment. Is it save to drive like that? Absolutely fucking not. Does he car(e)? Also absolutely fucking not.
