i must admit that prior to my accident it was a matter of comfort, if the belt didnt sit right or was uncomfortable( ie the ones in my toyota tacoma p/u ) i wouldnt wear them, When the belt in my suburban wasnt working that day i wasnt that worried, was no big deal at the time i'ld foix it later, even though that wasa comfortable seat belt, My old ford truck i had before the suburban was one that had only lap belts they were ok, not as good but ok, now it doesnt matter what vehicle, whos driving, where we going or how far,, even if its across a parking lot i buckle up. Any one who has ever experienced the need for a seat belt and if you needed it you know it..lol.. knows why i waer em every where, anyone wants the link to my story can pm me for the link.
