From here in the Seattle area it is about time to put an end to the bike madness, even if only through a token tax to be paid by those who spend too much on a single item (with their own money!).
To say that bikes have no impact on roads is definitely NOT TRUE in the USA. Most of the bike paths in the cities are part of the roadway, it costs just as much to pave those four feet or so dedicated to bikes as it does for the remaining forty feet (on a per foot basis, of course). It is not like the Netherlands, where the bike paths were not a part of the roadway.
