E.g.
- Switzerland and (somewhat surprisingly) UK: pretty good, people doing idiotic shit is rare enough that I'll usually comment on it if there's another person is in the car. If someone is riding my ass I'll make the effort to try and shake them off.
- Italy and Spain: horrifying, impossible to relax at all on the highway, having someone 2 car lengths off your rear bumper is the default condition.
- France and USA: somewhere in the middle where there are a lot of idiots but they are still the minority.
Subjectively, the USA feels much more sketchy because the rules are so much looser around overtaking.
