I heard she just walked up to him and said, "You've got a little package, don't you?"
You're trying to make a Dad joke, I know, but the driver is female.
My experience from working at bars is that, stereotypes aside, young females are more likely to go hands on then young males because they are much more likely to have no real consequences to physical violence. Some, like this driver, face legal trouble, but mostly they just get told to stop. Also, if a female attacks a male odds are good they won't even fight back.
Some urban subcultures are even more likely to throw hands.
