The lack of more use of bicycles in America is due to........
A nation used to cheap gasoline to fuel oversized cars.
A decided lack of any nationwide mass transit system.
A lack of any state or national road plans that are bike friendly.
A move of the workforce to suburbia away from central farm & city work.
A culture that thinks of bikes as "toys' for children and not
as a useful means of individual transportation.
In general the rest of the world can't afford ,nor do they
need, cars in the numbers that Americans are now forced to
buy by the changes in our country since WWII that saw our
rail and cities decline.
