Exercise a little common sense.

Don't drive where you shouldn't be.

Don't park where you shouldn't be.

Don't make people mad for no reason.

Exercise a little sense when it comes to what strangers to get close to in public car scenes.

Don't act like the biggest, baddest, fastest, quickest, smartest...when everybody knows you're not. You're just going to piss people off and make a target of yourself.

Don't be a part of the cheap parts scene and don't associate with people who sell cheap parts.

Don't make the car the biggest part of your life. Don't make the car your raison d'etre because it is, after all, just a car, a material object, and it should not be the end of your life that a car has disappeared.
