A group of friends were all caravaning to another friend's house for a party. 3 of us were following another car but some dude in a Jeep cut in front of us and we couldn't see where our friends were going. So we changed lanes and passed him. The Jeep dude decides that we had apparently cut him off so he pulls out from behind us and cuts us off big time. On a suburban street no less. Then he sticks his right arm out and gives us a thumbs down.

It was the lamest cut off I've ever experienced. So all three of us in the car flipped him off from behind.
I also had one lady in this TEENY lil Miata lay on her horn because she wasn't going fast enough for me to merge behind her. So I passed her with plenty of room. There was no way I would have hit her because she was going too slow.
