#4 ... I rest my right foot on the accelerator pedal
#2, #3 ... I find that when ever I've got a bit of clear road in front of me I give the car a little (quite a little) more juice than I normally do. I particularly like to do this when I'm first at a stop light. No wheel spin or anything, just some very brisk acceleration (then look in the mirror and see how far back everyone else is)!
