I really don't feel safe riding on a bike path or sidewalk anymore, both for bike safety and keep from being isolated. All the bike paths around here aren't really safe for cyclists. They have lots of joggers, walkers, kids just learning to ride, moms walking with young children, etc. My road bike, which can go 20+ mph, really doesn't belong in such a setting, ever. Bicycles are vehicles and are safest when defensively on the road, just like driving defensively.
