The other fears are mostly irrational, though. This one doesn't appear to be: it seems to be a cultural thing that US bikers are OK with riding next to cars, while to me it just seems... not prudent. How does that protect me from a car just ramming into me from behind? There just doesn't seem to be anything I can do about that. I'm always relying on the hope that the driver behind me is paying attention and I'm not big on hope. Riding on the street to me is usually very rattling because of how many cars repeatedly pass me, it doesn't really reduce my fear.
