Raging Bike measures individual cyclists contribution to the environment, the money they save and the calories they burn, by choosing to cycle rather than taking a car or bus. * As bike commuters for many years, we got sick of car drivers cutting us up, using bike lanes, general abuse, and the treatment of cyclists as second class road users. When we got to work we would find that venting our frustration to our colleagues (in the main car drivers) provoked little sympathy. Hence the rage corner were devised as a harmless catharthis for our fury. Please post your experiences!
