Lit cigarettes being thrown from cars

[darrsi]

I have had to bite my lip several times over the years as far as windscreen wash is concerned, but have come to a loose conclusion that not all people are malicious and some do innocently just want to clean their windscreen but due to movement of the car added with the wind the only place that the liquid can travel is straight over the car and into ANY vehicle behind it.
Slightly different shenanigans when you're sitting still behind a motor at lights and the jet of liquid flies totally over the whole car into your face and you can see a couple of dipsticks sniggering in the mirrors though.
