#1 The guy who pulls up next to you at a stop light/stop sign and pulls off like a drag racer. Nothing, I mean nothing, is more impressive than somebody who can outrace a bike with their car.
#2 The people who pull up to a stop sign and come to a complete stop. You think, "great", you pull up to the stop sign ten or fifteen seconds later and this person, no doubt thinking, "what manner of strange beast is this on two legs sans engine?" stares at you...and stares at you...and stares at you...You wave at them to go, and they stare at you...Finally you nudge your way into the intersection and they take off as if you had just hypnotized them with your mysterious bike mind control and they managed to break your mind-grip on them at the risk of their sanity. Usually a really confused-looking old woman.
