I will ride the sidewalk for a short distance at the end or start of my trip, like from the nearest driveway to the door. Otherwise I stay off the sidewalk. It is a very slow place to ride, dangerous if any pedestrians are around, and often illegal. Very occasionally if I find myself on a section of road that is too dangerous to ride, I'll escape to the sidewalk, either walking or scootering or riding slowly, but this doesn't happen twice. I learn and don't go that route again. There is almost never a destination with only one road to get there.

For people who ride sidewalks regularly, I have to ask:
- Do you ride >5 mph? Riding much faster than that is dangerous, among pedestrians and cars in/out of driveways and people darting out from shop doors.
- Wouldn't it be faster to take an alternate route, on roads, where you can ride 15-20 mph? Even if it is 3X longer.
