    Speed bumps exist to slow down vehicles, in this case for pedestrian crossing.

    Do you think it is more useful to slow down a 1-2 tonne (or more) chunk of metal from 50 to 20 km/h or a combined 150 kg vehicle from 30-20 km/h? Which would be worse to get hit by? Which has the greater stopping distance? Which can turn to avoid obstacles faster?
