I hate to unclip. I mean, it just ticks me off to have to start cranking when the light turns green, AND find the pedal. I'm not very good at it. Plus, I suck at trackstanding too.

Today, I tried holding onto the car next to me while we were waiting for a green arrow. It was a pickup, and I was leaning on the edge of the box, so I don't think it bothered him. He was talking on a cell, and after a little bit he noticed me and looked back. I gave him a wave, and he didn't seem to notice. When the light turned green, I fell in behind him and made the left.

Does anybody else do this? Do drivers get upset or unnerved (and thus dangerous) when you do it? I'm considering doing this more regularly, if I'm presented with the situation.
