Bicycles and bicyclists were considered curiosities in most cities. Bike lanes and paths were recreational rather than pragmatic. Urbanization, economic pressures, and health and environmental awareness have driven an increase in bicycling as transportation. The initial reaction is frequently a challenge to the existing auto-centric infrastructure. The reality, however, is turning out to save money and lives. Building bike lanes costs money and people do have bicycle accidents, but at least $6 is saved for every $1 spent, and the incidence of total commuting fatalities goes down because car accidents are more hazardous than bicycling accidents. Get people out of cars and onto bikes and many benefits ripple through the community.
