this doesn't involve anyone in a car but it does involve a cyclist. the other day i was trackstanding through a light and this lycra-roadie bro was stopped at the light in the other direction and he gave me the weirdest look..you know how a dogs head goes sideways and it gets that dumb look on its face when it seems something interesting..yeah that's the look the guy gave me. there really aren't any fixed gear riders in this area at all so it must have taken him a second to realize how i was doing it.
