I’m sick of hearing how the g forces on racing drivers require them to spend six hours lifting weights with their necks every day before selling some more after-shave and watches (and that they still have to strap their helmets to the vehicles during races, just to get around corners).
Today’s invention is a gimbaled driver’s seat which rotates during high speed cornering, so that a driver’s body is more closely aligned with the direction of centripetal acceleration, thus lessening any asymmetrical stresses and allowing safer cornering.
Trains which have tilting carriages, it seems need to tilt quickly, just before entering a curve, in order to limit motion sickness:
