I think it's really funny how humans can't help but use round numbers.
30 kph = 18.64 mph
20 mph = 32.19 kph
So safety rules around the world are based on arbitrary length systems. I'm all for lower speed limits for safety but I feel there is still things to be worked out in suburban settings where long arterial(?) roads carry large amounts of traffic in large cities.
