something i said on another forum a while back:
i smoke, and sometimes it has affected my driving, lit cigarettes dropped, brake immediately without looking, dont want to burn the seats or the jeans or the mat, feck everyone else, fling open doors and look for it before the car goes up in flames, a bit too many times (one of the reasons i am looking for a fire extinguisher)
i tend to have my cigarettes ready in the ash tray if i want one, usually when the car comes to a halt would i light a fag or get the passenger to do it for me, on certain occasions i have rolled a fag on the motorway doing 90, who cares, i need my nicotine fix
you can hold the steering wheel with both hands and still smoke, don't need any hands for smoking as long as one does not mind the smoke in their eye and causing a collision. i tend to keep the window open, have wind/rain deflectors so the window is open all the time i am driving it, even at 150mph, which creates a vacuum thereby sucking everything inside outside, and that helps when not using the hands to smoke.
i would not recommend doing it, its dangerous, but i cant help it, addicted to the nicotine
