Yes, it's called cycling amenity. How you feel in any given situation.

You sound like someone who prefers a high cycling amenity, and choosing an alternative route to ride is a good idea.

There are cyclists who can ride in areas of low cycling amenity and aren't afraid to take the lane, and can handle the aggression handed out by others, including fast, close passing and the horn-blowing. Generally, they have ridden for a long, long time, have a well-tuned eye for bailing out, and know what to look for. Bailing out sometimes does indeed mean choosing another route, or getting off the bike.

One of the bits of advice that is emerging with BFs is to not provide too much detail in a thread on the incident and how you feel afterwards.

If something untoward does happen as a result of this accident and you need medical intervention, and assuming you got the name and address and insurer of the car owner/driver (you did get all that, didn't you?), you might need to seek restitution.

And if lawyers get involved, and after reading the info on this thread, you might not have much recourse.
