wow, this thread left me in stitches, thanks for the great laughs as i could relate to nearly all of'em.
187. you get mad and curse at the car in front of you when going downhill if he has to turn or use his brakes because it forces you to use your brakes robbing you of your precious downhill momentum
188. when coming to an auto-stop in traffic, you look around at the other cars to see if they've noticed that your engine has turned off.
189. you've replaced your spare tire with a can of Fix-A-Flat because the spare tire was too heavy and lowered your MPG
190. you've removed your can of Fix-A-Flat for the same above reason

(and replaced with a AAA sticker, in case that moment should occur)
