When I ride in the parking lane motorists can pass with out going into the oncoming lane.
Usually there are no vehicles parked on the steepest parts of the hill when I ride through & not until further up where the hill flattens out & I can pick up speed or it is easier for motorists to see up the hill to pass me in the oncoming lane if I have to merge to the left to pass a parked vehicle.
In other words for my own safety I have to go against the VC way of riding to keep myself form getting clobbered by a motor vehicle & to keep the peace between cyclists & motorists.
This IS NOT VC, it is how ever AC, or Adaptive Cycling, which is adapting my riding to the conditions I am riding in & not asserting myself to taking the lane because of & based on a principle that someone, (JF), wrote a book about.
I ALWAYS ride in an AC style. NEVER VC.
