Bumping up the costs
Has anyone ever done the CO2 calculations on speed bumps? If you decelerate and accelerate (even be it sensibly) there is a CO2 implication in the extra fuel and brake wear (presumably CO2 is generated when creating brake pads). If the driver doesn't slow (much) then there is mechanical wear involved - hence extra CO2 in the replacements. Cement requires large amounts of energy to be created - how much per bump? The list goes on. Doesn't sound very green, does it?

Yes, Peter DeNayer has, using his fuel consumption kit. He sells his reports, sometimes to What Car. The other undesirable effect of speed humps and speed cushions is that tremors from vehicles crashing over them breaks up the substructure of the road and the foundations of adjoining buildings.
