This Cadillac was a boat as well, and all the weight was in the front end. It wasn't the first front wheel drive, but it was one of the first, so not only was there a 500 CID engine under the hood in the standard configuration, the transaxle was up there too.
When that wheel folded up and the front of the car landed on it, the car ground to a halt. I was shocked.
So shocked I forgot to put the car in park.
I got in the trunk and pulled out the jack and spare and started to jack it up.
That Cadillac had a hood that wrapped all the way around to the grill.
I was on a pretty flat spot and the car only started rolling back after I got it almost high enough to put the spare on.
Now visualize where a little taller bumper jack is going when the car rolls back...

Now imagine not having another jack to extricate it.
