That's very true, I trackstand a lot when riding my fixed gear and I noticed that most drivers are a little confused when they see me do that, some get angry, some just shake their heads. I still believe that trackstanding is much better then riding around in circles. I've seen this too many times...I'll stop at the light and trackstand and all of a sudden some guy with clipless pedals comes up ahead of me and starts wobblying and riding circles all over the place, they look so dumb when they do, I just shake my
head. If somebody doesn't know how to trackstand then they should unclip and put their foot on the ground and wait, don't wobble and ride around in circles because it just looks dumb and idiotic.
