Actually, all I need to know is the controls and the daily maintenance, like putting gas in it. All the rest can be left to a specialist. I don't have to care anything about why pushing 1 pedal makes it go forward and the other slows it down. Or how turning a wheel changes the direction. Or how various buttons activate various features. They just do, and that's good enough. (I'm not actually ignorant of these things, but it certainly wasn't necessary to learn them. I chose to. It hasn't really helped me much, except to satisfy my curiosity.)
