Littering is littering regardless of where it is.
It doesnt justify you to b any better than the Joe blow that does it on the streets IMHO. Its just like someone trying to justify they arent a drug addict because they dont do the "hard" stuff and is only on the "green" stuff.
I smoke, i ash outside the vehicle, i throw my buts in a container (those metal Extra mint containers work a treat). And to those who think they can smell a smokers car a mile away. Think again.Most smokers cars (ppl who take pride in their appearance & love their cars) would usually have a car thats cleaner than most and most would also always have an air freshener in the vehicle.
Working in the car industry i see 1000s of cars and can honestly say that some of the non smokers cars are worse off than a smokers car.
Just getting a bit sick of the do gooders picking on smokers all the time.
