Is it time to start calling out bad cyclists?

I'm getting increasingly annoyed by people pulling up on each side of me at the lights such that there is one person 1' to my left, and another 1' to my right. What's wrong with staggering a meter behind me?

Taking off between two wobbly nodders can be scary, so I'm then having to gun it as soon as I see orange. Crap.

There is a simple solution to this. Everytime you stop at the lights just start doing an impromptu aerobics routine. Fling your arms out to the sides like the do in that bit in Flashdance where she's on that chair, that and wave them about a bit. Make it look a bit more disco by throwing in some head movements and you have the triple bonus of people not willing to go near you 1) as you are likely to hit them during your on bike dance routine 2) they don't want to get too close as they think you are crazy and 3) they'lll stay behind you so they can safely laugh...
