Studies in Denmark and Copenhagen show that roads cost taxpayers money but bike lanes saves taxpayers money.
They design there road systems to properly control pedestrian, bicycle and motor vehicle traffic so there is less chance of carnage in the street. When there is a problem they work with the public and most people are on board with the changes.
We have yet to come near this kind of implementation of integrating the roads so they are safe for everybody. Our heart is not in it. Much of the bicycle infrastructure is poorly implemented and incomplete. It seems like someone complains and the politicians pop for something to quiet the complainers. The difference it seems it they care about everybody in there communities and we only give a crap if we get a piece of the action.
