Before everyone denounces this whole idea, remember this about speed limits in Europe: they are not kidding that exceeding the speed limit is dangerous on European roads. Try driving a "normal" car exceeding the posted 60, 70, or 80 km/h limit on a continental European road and you're liable to get into trouble very quickly, unlike American roads, which tend to set the speed limit way lower against the potential limit for safe driving conditions.

80 kph is only 50 mph. Where’s the danger?

“they are not kidding that exceeding the speed limit is dangerous on European roads”

Yeah..
No kidding...
Got that lesson on a German road south of Vilsek, with opposite banked turns.
