Huguenot, your stats are from the US, so they don't really count. Nor does the 'think of the children line'. Your kids shouldn't be playing on a bus route anyway. But those 'tabletop' humps Kilmore is referring too aren't so bad on the back, it's the cushions and sleeping policemen that cause trouble: they delay ambulances, dismount cyclists and motorbikers; render cars unroadworthy and cause motorists to swerve in order to straddle the darn things.
