I don't smoke, but I know what you mean about rain coming in whilst driving along. Sometimes its just nice having the window open, and letting some "fresh" air in, but rain also follows. So up goes the window. Anyone know a car that this doesn't happen on?
As for water dropping in when you open the door - my solution is to just run my hand along the curve of the roof just above the door to flick-off the water. OK, wet hand, but less wet than all the water dripping on your seat when you get in.
Sometimes I forget to flick the water off. But if its been raining, I drop the windows down and back up, to clear water off them. If you do this after just setting off, with lots of water on the roof of the car - blimey its amazing how much f###in water comes pooring in. Switches, door panel, seat, leg all p#$$ wet through!!
Sunroof - don't have one, but very funny stories from those who do!! /ubbthreads/images/graemlins/smile.gif
