Yeah, we have to be careful.
Some vigorous shaking and sincere pushing in the X and Z directions help reveal basic weakness
and stability deficiencies.
Logs on end are easy to split if a wedge or rocker seam presses hard into the end grain.
That's the way log splitters work.

The solution is to place a 2X8 or 2X10 as a pad between the car and log, with its grain perpendicular to the sharp edge. Better yet is a pad of 3/4 inch or thicker plywood, because the grain of the plies alternates, making it mighty split proof.
A log or stump lieing down is a wheel.
Dreaded concrete blocks have a wonderfully large 8X16 inch foot print which, when placed on a plywood pad on graded soil, is mighty secure.
Also with a cap. Real nice under a tire to raise the car 9.5 inches.
B sure and orient the block NOT like this.

I scrape the grade fairly level and flat and use at least 3/4 inch thick plywood under jackstands or my floorjack when I use them in the yard.
