According to the expert witness that I generally used in auto collision cases, the real factor in reducing injury and death is getting yourself out of the plane of impact.
In other words, get up high and most of the force of the impact will pass beneath you.
(I drive a mildly jacked up F-150 4x4. A little extra advantage in muddy pastures, too.)
