Smoking or Non Smoking.

[uranium_death]

Smoking is a habit that destroys your lungs, rots your gums, can cause blindness, gangrene and a host of other funky diseases.

There's the health issue.

Back when I worked at a cabinet maker, the foreman (who was the ****ing laziest fat ****head I ever met in my life) asked me to go to his car to get some money for a sausage roll. Now this guy smoked more than he worked. His car smelled like a camel jizzed in it, then took a dump. Smoker's cars reek.

In terms of driving, drivers who smoke while driving almost always throw their butts out the window, as well as flick their ash. I frankly don't care if smokers choose to destroy their insides...just don't destroy the outside (being what is left of Earth) with your crap.

Smoking in cars isn't as bad as a phone, as phone conversations MAY cause drivers to concentrate more on the conversation than the road. Smoking is a non-interactive activity that involves sticking a paper stick with tobacco in your mouth and lighting it. The risk is not as high as a phone.

And stiff **** if you burn your pants.
Wear shorts instead and burn your legs. They'll probably get amputated in 30 years time. :P
