Anyone who throws any rubbish out the car should be shot!!!
On numerous occasions at traffic lights I have got out my car and picked up a fag butt just flick out the window by the driver infront of me. I then re-presented it them and asked politely that it is disposed of correctly.
In the majority of times they are happy to take it and deal with, a few people have been surprised that someone is knocking ion the car window and not suprisingly I have been told where to go several times.
Am yet to be fully confronted as they all know they are in the wrong. It also helps being 6ft 2 and 19 stone with a skinhead, kind of puts the tossers off getting our the car and beating me to death.
There is no need for it at all.
