I remember getting sick to my stomach the first time I smoked while driving. You might want to stick with something a little more mild if you haven't tried it before. Plan ahead for your ash disposal, have an large ashtray or cup for the amount of ash produce by a cigar. Otherwise it will end up in your lap, or you might have to ash out the window while possibly going 70mph and it blows all over the place.

I also sometimes go out for lunch and stop by a park and enjoy a nice smoke in my truck with some music playing...so stinkin nice...
