In all fairness though, you strap on the plane because gravity pulls you in directions that includes those that are not into your seat. Odds favor gravity always pulling you down in a car. You are exposed to being separated from your seat dozens of times on each and every flight as a normal course of operations of the airplane, but the exposure of being separated from the seat of your car only occurs due to a mishap of some sort. There is no question that remaining in the seat of the car, or plane, does alot to improve the survivability of the forces that would separate you from the seat, but those forces always exist in a plane whereas they only exist in a car during situations that are associated with an emergency. To be sure, an emergency is an unplanned situation and it's the unplanned situations that we need belts for in a car. In a plane, the belts help us during the planned situations. |
(loosely speaking) back in high school would indicate that on cannot really
rely on gravity to keep one's butt firmly anchored to the seat even in
terrestrial vehicles such as the Jeep. We hit an unexpected ditch one
afternoon and a buddy's head deformed our shiny new top right smartly.
Then too, some of us prefer coordinated flight when we are at the controls
with excursions into the negative g region as a planned maneuver. Of
course, when I flew with students I always hitched the harness as tight as
I could - that was sort of like planned turbulence.
I'm a believer in seat belts but automotive hardware design leaves something
to be desired in that area.

thing pulls 1.4 g's at all time that you are not just going straight and
accelerating. Couple that with about 4 " of total suspension travel
means I have to strap my driver in using BOTH hands on the seat belt
cinch points. Driver comes in with bruises.
Heh, we both something with big tires, chome/aluminum wheels, and push
the envelope. He gets in trouble at 160 mph, I get in trouble at 3 mph.

I can tell you don't drive the the Porsche GT3-cup car I wrench on. That thing pulls 1.4 g's at all time that you are not just going straight and accelerating.

Well, yeah, I was not thinking of that. I was thinking of the car I let my
wife drive. The bottom is pretty predictible.
