Fun fact. In Lithuania there was a standat speed limit 60km/h. But we have this curiosity that if you exceed speed limit by less than 10km/h, there is no fine, just a warning. Basically "hey, could you please not"

Because of that de facto speed limit in streets was 70km/h. So to combat this, currently we have speed limit 50km/h in cities, which translates to de facto 60km/h

It's been the same in Germany. Literally everyone drives over the speed limit all of the time. 30km/h is somewhat stuck to when it's near a school but everywhere else people just drive faster because the fines were ridiculously low for the longest time.
