Horses were raced on tracks in the US on tracks before cars. Early car racing was on the same tracks ("dirt tracks"): so they went the same way as the horses = Counterclockwise Bicycles just followed the same way.< BICYCLE CONTENT >
Road racing (sports cars) came from England/Europe and followed the way it was done across the pond in "the Mother country"
