I haven't read all the posts, so many, so apologies if this has been already said, not only dangerous to smoke whilst driving, but the discarding of cigarettes whilst still alight out of the car windows is totally irresponsible. Roadside fires etc, even the odd leaky fuel pipe that owners don't realise they have. Flashed a female driver with a car full of children , pulled along side her , ignored her swearing at me and pointed out to her fuel gushing out underneath her car. Just as well she didn't have some inconsiderate driver in front of her throwing out lit ciggies.
