Check out this letter in the recent Portland Tribune:
Bicycles are nuisance, and their riders rude
The bicycle’s contribution to clean air is at best infinitesimal and is probably negative because bicycles, bicycle lanes, etc., slow traffic and increase congestion. However, the bicycle lobby continues to receive the support of city, county and state politicians, a tribute to the power of small, vociferous, self-serving, special interest groups. By the demeanor and actions of the majority, bicycle riders could best be described as aggressive, arrogant, freeloading outlaws.
