As the general driver for my carless theatre friends and family members, I've established some basic rules:
1. I decide who gets shotgun. If a girl is pregnant, she gets it by default (unless she's my brother's awful girlfriend). I do try to keep the rotation fair to everyone, which is more than I can say for those idiots who yell "shotgun" the moment we get into the parking lot.
2. I decide what music we listen to. If someone really loves a song that comes onto the radio, I may consider leaving it on. Unless it's a song I detest. Then I change it over the protests.
3. Any side/backseat drivers will be told to walk. Including the aforementioned pregnant women.
4. I keep a trash bag in the car for a reason. Drop wrappers on my floor, you pick them up with your mouth.
5. When giving me directions to a place I've never been, tell me at least two streets before the one I'm turning onto. I've almost gone into the ditch a few times because a friend said, "Oh wait, it's this road, turn now!" when it was slicker than snot on the roads.
6. Distracting the driver will lead to a slap in the face when we've parked.
7. Seatbelts will always be worn, even if it's a short trip, or we go nowhere.
8. I hate the smell of cigarette smoke. I have to put up with it in the theatre and the restaurant where I work; I do NOT want that smell in my car. Period.
9. Mocking my bumper stickers will revoke your riding rights.
