If not mentioned before:
1. The Me "first" types, the ones poking along in the right lane that all of a sudden speed up so that you can't pass, then as soon as you tuck in behind them, again, they slow down to a crawl.
2. the Turn-in stoppers, turn off of a road and then stop or slow to a near stop once they have turned in...into a parking lot, onto a cross road or whatever, kinda like they knew they had to turn but now what?
3. The insta-brakers. Do not realize that the Unimog they just cut off does not have the same braking capacity as them. In this particular example, Darwinism takes care of the problem, Mog 1, others 0
