Why is it legal to smoke a cigarette while driving a car?
Cigarettes contain many toxic chemicals and the effects are quite dramatic. It isn't called "spin" for nothing.
Smoking requires one hand, which is one of the reasons mobile phones are not supposed to be used by drivers.
Smoking involves containing a small fire that could easily escape if the driver has to pay extra attention to the road at some point. I have seen drivers roll and light cigarettes while driving.
Cigarettes thrown form cars cause many roadside fires which sometimes expand to very large fires.
Has any research on the effect of smoking while driving ever been done or are the tobacco companies too powerful?
