Smoking or Non?

There was a new law passed in California: We are no longer allowed to smoke while driving if there are minors in the vehicle. We already can't text, use the hand-held portion of the phone, or obviously drink alcohol (which was legal not too long ago). What's next? Maybe they will place a volume governor on vehicles. I'm not a smoker, and it is actually very gross to me, but I certainly would rather have my freedoms protected rather than have a disgusting habit banned. At first I was all for the smoking ban in restaurants, but the more I started thinking about it (and listening to my mother and sister), I realized that this is a deliberate infringement on our rights. Any thoughts?
