I always maneuver away from cars while on my bike.
Either by going fast enough to get away from the flock of cages or going slower.
So what if I zip through the cars? That's why I'm on the bike, If I want to be stuck in traffic I'll drive the car.
When I'm driving a car I could care less if I do not have time to notice the bike that passed me.
It happens all the time in places that have yr round motorcycle riders.
Tailgaters? Either in my car or bike If I cant move out of the way I slow down, heck I've even stopped.
The only time I usually get tailgated is if I'm in the fast lane, so I figure why not move over and let them pass when safe to do so..
Last week I made a rare trip to CA and was being tailgated by an idiot in a mall parking lot, I was going 10mph, ( with my hazard lights flashing) looking for a drug store. The guy rushes up behind me and honks. I ignore. He gets right up behind me and turns on his brights, so I stop dead. He honks some more then has to back up so he can get around me.
If you tailgate me, fine, be prepared to get stuck behind me.
