When I ride my bike to work, I ride down Drake ave. to the Parkway then cut behind the Wal-mart, past the Honda dealer and take the foot bridge across the creek to Lowe Mill. Drake has four lanes for traffic plus a center left turn lane. By moving out into the right hand lane a few feet, the cars passing me are all in the left hand lane. I also do that trick of turning my head to let approaching cars I know they are there.
Because "rush hour" traffic is way too hectic on that route, I leave the house early. Those soccer moms in their SUVs are very dangerous as everyone of the drivers is on their cellphone, putting on makeup, yelling at the kids in the back, and drinking coffee.
Since the country roads are often curvy and/or hilly, I will wave cars around me when I see the way is clear or hold my arm out to let them know a car is approaching. Nearly everyone waves at me when they pass and I wave back. never know when I may need to hitch a ride from one of them.
