"Quite often there is not physical possibility of legal parking." By the same token, quite often there is not physical possibility of legal cycling OR driving.

"Quite often there is not physical possibility of legal parking." By the same token, quite often there is not physical possibility of legal cycling OR driving. Courtesy is the solution indeed, yet the rhetoric on the issue seems to point the finger at cyclist more than other parties involved. The problem with the delivery truck/bus blocking the lane is that its easy and much more safe for a car to take half of the extra lane without obstructing the flow. This is a much more challenging a maneuver on a bike. Finally, these vehicles block the bike lane and then half of the right lane. Imagine if a truck was wide enough to block the entire two-lane roadway and force motor vehicle traffic to precariously dodge traffic going in the opposite direction. Not a bulletproof analogy, but worth considering...
