Smoking really os related to cars and driving. Smoking hurts your driving ability in 3 ways.
!; The distraction factor, fiddling with getting cigarettes out and lit, dropping them or hot ash on the seats all distract the driver. In my casr it was worse because I smoked a pipe, so there was cleaning the pipe or at least knocking the dottle out., getting the tobacco out , filling ,tamping and lighting.
2: The film it puts on the windshield reduces your vision at all times and in damp weather it can blossom onthe inside of the windshield and if you try to wipe it while driving it makes a real mess.
3: The most important reason. it reduces your night vision. Nicotine constricts blood vessels. I hchanged from cigarettes to a pipe in mt 20s because pipe tobacco was cheaper, but because you inhale cigarettes, I inhaled the pipe. If I lit up a pipe at dusk I could actually see my peripheral vision fade in from the sides.
