Gonna get flamed, don't care.
I ride on the sidewalk all the time. Why? Much safer for everyone involved. Safer for me as a cyclist, safer for the motorists who don't have to be distracted by their fury at seeing someone on a bike.
Here's the thing, I know I am breaking a bylaw (before unleashing sanctimony ask yourself how often you come yo a complete stop at a stop sign - I know all of you do all of the time.)
When I ride on the sidewalk - speaking solely of myself - I ride slowly, I slow to a bare crawl when coming up on blind corners or entries to yards. If there is a pedestrian I get off well ahead of them and walk past. I have been thanked for this and my response is a smiling, "No need, it's a sidewalk, not a sideride."
Is this a perfect solution? Nope. Is it the best solution to keep me safe? Yes, and it is my responsibility to look out for the safety of others in the sidewalk.
Given that not one person I've passed has ever complained and, as I said, people have expressed appreciation, I don't believe I am acting in an unsafe or discourteous way. Illegal sure, so is jaywalking and not signalling which I see dozens of times a day.
Rail away to your hearts' content. It's not going to make me change
