To one wheel, I'm referring to hunt club, bingo, but really, take your pick. Our scenic 'park'ways, the downtown, prince of Wales, fisher, island park, merivale, Woodroffe, greenbank.... name an arterial around here, there will be people sitting on it in their cars. Clown driving at its finest, and really quite sad. I'm guessing people stick with the cars out of a mix of fear of traffic, perceived difficulty of logistics of cycling, cheapness of driving (because most expense is fixed, except gas), and overestimating how fast their car goes based on max speed rather than average. Maybe also some hope for a good traffic day. If only they could see how safe and easy it is to bike. My contribution to fixing this is to help at least one person start riding a bike every summer. Not always successful, but I've got two coworkers who are interested in giving it a try this year.
(Btw, I think we met around the smokey straw bales at the cfsc winter ride.)
