I've found an easier and cheaper way to beat any on the street. They pull up, do the dance, and I slightly smirk, give them that brush off look, the one where you scrunch your eyes a bit and move your lips into a side sneer, as if they're not worthy, and invariably they back off a little. It's really pretty funny. If they push me on the road, I'll let them get a bit ahead of me, and then sneak up on them and pedal it, and I'm gone before they even see me. That's fun too when they pull up at the next light and look over, then I just do the one nod up, look away and go about my business. They just aren't quite sure what to make of it.
