Feel free to agree with me, close to 99% throw their fag out of the car when they have finished.”
I'd be in favour of cigarette smoking in vehicles being made illegal, since it's obviously a major distraction if you drop it, the burning end falls out, or it blows back into the vehicle when trying to throw it out of the window. Cigarette smoking is already illegal in all PSVs AFAIK, so this would be the next step.
The other thing is cigarettes thrown out of the window are a fire hazard in dry weather.
Ideally in a moving vehicle you should be driving and only that. No talking to other passengers, no in-vehicle entertainment, no sat nav, no soft drinking, no smoking, no mobile phones etc., as they are all distractions. Obviously that is never going to happen in full and one has to be realistic, minimizing the number of distractions. Many roads are so busy these days, that's the only way.
