I think your success at driving while ripped depends on your comfort level. I've never had an issue at all. When I drive, I leave the side windows up but open the roof. So as I smoke, it just goes through the roof. I try to find nice 'comfort' zones to drive in....nobody around me for at least 2 car lengths. When I'm done, I put everything in the center console and drop the rear-seat windows to let everything air out. Driving wise, it's really no different than when I drive sober. The only real difference is that asshole drivers don't bother me as much. I'm just crusing in my own little world.
