drinking impairs judgment and physical reaction time. Smoking does not.

The bans on cell phone use in the car are because of the distraction caused by cell phone use (and, incidentally, I do not agree with those laws either, because we already have laws on the books that deal with inattentive driving).

The proposed ban on smoking with children in the car is for health reasons. It would not ban smoking in cars altogether - only those cars with children as passengers. If the focus is on the children, then it's logical to assume that line of thinking could be extended to include home use of cigarettes in the presence of children.
