Airbags. Clever idea. Puts me in mind of the Larry the Cable Guy CD I was just listening to.
"My sister was eatin' all them corn dogs at the fair there. On the way home she farted so hard it set off the side air bag. Then OnStar called and told us to pull over immediately and take a tuck and roll in the median! They thought the gas tank exploded on the Merc'ry Squire. Good Law-erd!"
