What's your experience with counterflow - going "the wrong way" on an one-way street (when it's safe to do, of course)? On my way to work there is this one way street by condo buildings that I take when the bike path is snowy and icy (they don't clear that stretch of the path). I meet very few cars there, but a dog-walker shouted at me a couple of times that I was going the wrong way. If I were to go "the right way", it would be quite a detour. From some Dutch videos I could see that bike traffic counterflow is used there quite normally.
