When I used to smoke I wasn't looking and flicked my butt out the window right into the guys car next to me while on the highway.
Luckily he was to busy panicking trying to get the burning hot amber off his lap to be bothered with chasing me down
I felt bad about that though.
The one time I got really pissed was when I was trying to get over and put my blinker on, on the highway and this douche speeds up to block me like a lot of douche bags do for some reason, so I just gunned it and went in front of him anyway.
Well he lost it and was riding my ass, swerving back and forth like he was going to do something about it.
An opening came up on my left side so the a-hole zips over there and then gets right next to me and swerves at me and is all flicking me off.
I'm driving a full size company van at the time (no markings though) so I'm not bothered by his threats but what does bother me is I notice that his little son is sitting in the passenger seat.
This set me off for some reason, just seeing a parent be so reckless with their kid in the car with them, its one thing if he wants to be like that on his own but I guess I just drew the line at him having his kid with him.
So I basically kept next to him and rolled down my window and yelled at him something stupid like "way to set a good example to your kid there dipshit!" or something like that. He looked madder than ever after that but I didn't give a shit, I got behind him and tailed him for awhile and got back next to block him from being able to get around anyone, I must have had a pissed off look in my eyes or something though cause he stopped after a little while.
