Joey, here is a thread from April of 2006 where I tried to explain a similar situation and why it occurs...

It comes from "the notion" of motorists thinking that cyclists are supposed to get out of the way of cars... so motorists do this stupid move at stop signs to try to pass you by going around you just as you stop... and they do it by going into the other lane and end up on the wrong side of the road at the stop. It seems motorists cannot stand being behind a cyclist, even if you are going over the speed limit.
