Actually, it’s incredible, but I just heard it on the radio. There’s a car on uneven ground with the (standard?) jack and put itself under the cart. Of course, the lifter has cracked away promptly, and the car has pushed the dummy to death. Serial jacks are absolutely no good at all. For breakdowns I have a shear truck lifter from the hardware store with me. It can be used in several places of the body and the chassis. Then I lay it But don’t put me under the car. If I have to under the car, then I take the shunting lifter and put a thick chopper of about 1 m in length under the car. The block is so stable that you can leave the cart safely on it.
