I think your "people don't need to be polite" statement may have come across differently than you intended; perhaps I am the only one, but I read it as a statement of no need for politeness to other road users. A common example of that attitude is the left-lane-hog plodding along at the speed limit in the fast lane of a multilane highway blocking others from passing. They are focused on "following the rules" in lieu of being polite to those around them.

I do agree that politeness ought not to be taken to the extreme of inconveniencing others and/or sowing confusion and thereby decreasing safety.


Whatever vehicle I'm using, I always figure we're all trying to get somewhere as soon as we can, so let's work together to achieve that goal safely.
