My DH has this problem and he is 5'11". It is something about where on your neck that seatbelt hits. He tried all the adjustments possible, even the sheep wooly thing, now he drives with his left hand hold out the belt a little ways from his lap which pulls it out from his neck. I'm 5'8" and it hits my neck in a bad spot toowhen I drive, but not so much when I ride on the other side.
