My first car didn't even have a battery. I drove it for 2 years, always being careful to park on a hill so I could "pop it". So yeah, leave out the useless 12-volt battery, too. /s LOL
I wonder if cars from 50 years ago came with two wooden ramps that you could place next to the rear wheels and back up onto them before turning the ignition off.
My grandpa used to tell me about hand-cranks to start an engine[1] and maintaining a car prior to antifreeze (had to drain all the water from the radiator in the winter).
