We've had it here for years in school zones, you just get used to it. Doesn't bother me.Vehicle crashes and KSI road users cost the overall economy £TENS OF BILLIONS every single year.
Stopping distance at 20mph = 3 vehicle lengths.
Stopping distance at 30mph = 6 vehicle lengths.
KE at 20mph (2500kg vehicle) = approximately 100kJ
KE at 30mph = approximately 225kJ
In built up areas, a 20mph speed limit makes perfect sense.
