Those dust sheets do catch fire rather easily.
I had a Bedford Rascal van in my earlier years. On my way to a job, on a hot day. Both front windows open......and 2 small windows in back open.
Me having a smoke on my way home.......flicked my butt out of the window, (or so I thought) and carried on. 10 mins later I had passing motorists beeping me. I couldn't work out why. Until I glanced into my 1 and only functional wing mirror. My large dust sheet had been smouldering away, kicking out rather a lot of smoke, which was being dragged out of the back windows. I thought the smell was coming from the fields. (Lot of stubble burning going on)
God knows wot it looked like from behind, I imagine peeps thought I was on fire.
This is the same van I had to pee into.........but that's another story.
Well.....it's work related. :mad2:
