Is it that important? All technology gets better to the point of it just working, and when it rarely doesn’t, you contact someone who does. My grandfather could build cars from parts alone. My father could do most maintenance repairs and knew enough to understand what the mechanic was telling him. I know what video games and entertainment have told me about cars, but have no clue about it in real life. It hasn’t mattered. Cars are so reliable, I can just have AAA if I get in a bind.
