There are concrete blocks and cinder blocks. Cinder are weaker. The strength is turned the other direction.

True but neither have the tensile strength to be used as a vehicle support.

They make heavy weight blocks and light weight blocks. The light weight ones would support a bicycle but that’s about it. The heavy weight ones would probably support a vehicle but still not safe to do so. Also a concrete block doesn’t tolerate point loading at all. In a building they rest on level bed of mortar with flat lumber on top. Also a building has hundreds of blocks to carry the load. Putting a vehicle on 4 blocks is a way higher per block load.

Exactly. Cripple wall the way he has them. Not that I would use one in either direction when under a vehicle.

Then there was the guy killed by working under a bus supported by jack stands that were too small...

A REMINDER: Jackstands, vehicle ramps, and other such devices that are customarily used in pairs are most often rated in pairs. The single unit has half the capacity of the pair.

Marketeers like to advertise bigger numbers. Consumers are often ignorant of such concepts as safety factor, the difference between breaking strength and working load limit, etc. and the consumers put themselves in peril. They also may be unaware of good practices (such as chocking a partially raised vehicle) and compound the problems, sometimes with fatal results.
