If my BAC is 3 times the legal limit, chances are that any attempt to operate an unmotorized bicycle would result in a few feet of pedaling followed by a very low speed fall. However, if I were to put a motor on that bicycle, then I might be able to get to speed in spite of my level of intoxication.
