Obviously, I can't comment on how things are in your town. But Old Hippie pointed out prettly clearly the perils of sidewalk cycling. If motorists are so reckless and aggressive that they run cyclists they can plainly see right in front of them, I doubt that they are going to be watching out for bikes on the sidewalk as they whip around a corner. True, a slow and cautious sidewalk cyclist can anticipate these perils, and thus avoid disaster. Many don't, though, because they believe just being on the sidewalk is all the "safety" they need.

I think someone already pointed out that you have to vigilant no matter where you are. I agree. If you are an alert, experienced sidewalk cyclist, and the traffic culture in your town is hostile to cyclists who dare to use the road, fine, do as you think best. Where I am, sidewalk cycling is not a good practice.

Thanks for that defense. I was tired of it.
But now I'll throw in some more. The notion of cyclist/motor vehicle interaction leading to body bags is drastically overblown. A cyclist hit by a car - or truck or bus - does not even necessarily fall down. I don't. I can't possibly count how many times I've been hit but if I gave up each time I did this post would not exist. When you do go down there's no presumption you will be hurt. Many falls have no damage report whatsoever. If there is damage it is more likely to be paint polish or fabric than skin. When there is injury most cycling injuries are minor and heal. Collar bones and ribs predominate. Cuts, bruises, road rash. The occasional punctured lung. Yes there are severe injuries but they are not the norm.
My injury report for 300,000 miles is 3 stitches and a mild concussion (years before helmets) for injury accident #1, 50 stitches for injury accident #2. Most drivers do worse.

And yes I've had to crash the curb and lay the bike down in the road to avoid sidewalk riders blundering into the crosswalk. They think they're going as slow and being as cautious as pedestrians but they are not. And after you save their stupid butts for them they just act self-righteous and braindead.

The notion of cyclist on the sidewalk danger from a car coming out of a driveway that is blocked by bushes is drastically overblown.
