I smoke all the time in the car, one of my favorite places to smoke. Crack the drivers window, turn on fresh air on the floor, get a xikar travel ashtray and smoke away pal. Never fuck with the band while driving, get a good torch and light and retouch your stix above the steeling wheel, with your hands still on it. Dropping a cigar while moving is hairy, don't do it. Clean out the ashtray when you get out of your car, that will stink to high hell. Generally I take the band off and just chuck them on the street, I rationalize that's it's just leafs and they belong outside anyway.
