I can sort of sympathize with the horn honking (there's never really an excuse for leaning on it outside of impending accident, but a "hey, wake up" honk is okay in my book), but not the flying around you part. Most of the times I've come up behind someone sitting still at a green light, it's because they weren't paying attention and as soon as I honked, they went. So I can understand the "hey, wake up" honk if they can't see the obstruction. But when does illegally swerving around someone ever help?
