Seatbelts, front seat passenger is the Navigator whose responsibilities include tuning the music appropriately (no pop, rap, or country), giving directions and other miscellaneous tasks, Slug Bug rules apply everywhere and always when inside the vehicle, and Chinese Fire Drills at every stoplight (I don't actually do this but I wish I did).

I don't care about smoking and food so long there are no traces of either after the passengers have left. But no throwing cigarette butts out the window. You will put them out in the ashtray and then empty the ashtray or you will not puff. The smell of smoke goes away pretty quickly and doesn't do any harm to my car that I can tell.
