Cycle campaigning

Speed bumps are claimed to cost far more lives than they save.
In addition the proliferation of speed humps is responsible for the proliferation of large gas guzzling 4x4s, when London used to be full of Minis and superminis.

Speed bumps are blamed for causing deaths by people who are very silly indeed. It's a myth.

4x4s are a status symbol for rich people to cope with the Ribena slick outside Waitrose, I doubt their proliferation is caused by speed bumps, although you're right in that they do fly over them. Bring on the cameras.
