I suppose it would be mostly practical skills, cooking, fixing things. Usually had to be done by people themselves.
Maybe also mental things like navigating (with or without paper map) and remembering their daily and weekly agendas.
What other things would be a big difference with the people today?
I have to add that you’re 99.9% correct, there are rare people who only learned automatic and may only drive those. I know exactly one person, so it might well be 0.1% 😁
