Why not? What happens if you turn it off, then on again one minute
later?

I'm pretty sure that's because the compressor is looking out into a line which still has high pressure in it and is likely to "stall" when turned
on because it doesn't have the "running inertia" to pump past that pressure.
Waiting a couple of minutes lets the trapped high pressure bleed off
into the evaporator coil through the capillary tube or orifice so the compressor can start spinning again without stalling.

Same as starting a hot finicky car with a weak battery. Heat makes the piston rings expand, which makes a better seal in the cylinders, so the cylinder pressure is higher, which makes the engine harder to crank.

Agreed. And one thing I miss from my teen aged years when almost
everybody had a manual transmission car was the ability to "push start"
a car with an almost fully dead battery.

I once pushstarted a car by myself. To be fair, it was a two-door
Corolla. I had left the dome light on for a day or so and the battery
didn't take kindly to that.

Old style bumpers probably only worked once for anything more than a kiss, >> judging by the behaviour of my 1963 Bug (comparing front and back).
1963 is prolly too late. I was referring to "pre war cars". WWII that is. Many had vertically flat bumpers which could push similar bumpers onanother
car without significant damage.
It was the lining up, not the bumper design itself, I'd wager.
I've seen pictures of people using spare tires to solve a mismatch.
