Not to mention sidewalks aren't made for that sort of speed. I'm always rather baffled by the folks who show up on these threads and say bikes are "safer" on sidewalks. Unless you're a little kid traveling at barely walking speed, it just ain't so. Sidewalks have lots of obstacles (including pedestrians), curbs, and very low visibility. Not a good thing for a real vehicle.
I'll bet many auto drivers have thought exactly that about bicycles on roads.
I’d never expect a bike to ride on a sidewalk, I know that’s not what it’s for, though I usually did in college, when a bike was my main transportation. The road I commuted on was busier than our road, but not busily ~walked~. I knew where the bumps were, I did it every day.
But back to the issue, I’m as polite as can be, and don’t usually have an issue getting around them in the truck when I am just driving. It’s when they can tell I’m pulling the horse trailer, which means I can’t just ‘zip’ around them in half a lane, that I resent them not moving over to the shoulder. Every foot to the right they can move is a quarter mile of clear road I don’t have to wait for.
