Why do cars have ashtrays?
I know people smoke, but really: Why do cars have ashtrays? If you've ever ridden in a car with a smoker, you know they don't use the ashtray. They roll the window down just a crack, and stick the tip of the cigarette out to knock off the ashes.
If you've ever been behind a car with a smoker in it, you know they seldom put the cigarette out in the ashtray either. They just shove the damn thing out the window.
Of the few who do use the ashtray, most only use it for temporary storage of the butts. As soon as they get to a parking lot, they pour the contents out on the pavement beside the drivers' door.
So again I ask, "Why do car's have ashtrays?" What they really need is smoke alarms.
