Do you tell your passengers that they must wear them before you will move the car? Even backseaters?
Does your car have a beeping indicator whenever the front seat passengers aren't wearing belts? Do you find this annoying or inconsequential?

If you don't lock your car doors when driving, do you immediately reach for the automatic lock when someone appears to be approaching your vehicle when stopped at a light, etc.?
Do you use an MP3 player in your car? CDs?
Do you always sing along to your favorite music? When you have passengers? When the windows are open?
