Even then I still had to watch a few videos to figure out how to change my charging rate. It was hidden behind a number of hard-to-find settings and is disabled (silently) in many car modes (basically you can only change it when you're in "car on but motors not running and not charging")
It's the psychological concept of "maximizing vs satisficing" The former means to squeeze out the most of some item/experience while the later means being totally good once a thing is "good enough." We maximize or satisfice on different topics.
So I read the manual and I know stuff about our car that my wife doesn't. But because the car is safe, fast, and comfortable - it's maxing our her pleasure even if she doesn't know that some setting exists.
I think you might be conflating "satisfy" (as in "that satisfies my needs") with "suffice" (as in "that's good enough, it suffices for my purposes").
I might dive into the owners manual to make sure I know what grade of oil I need or for some specific need I have but I'm not going to sit down and read through an owners manual just so I can successfully operate a vehicle.
I have a license in my wallet that says I'm qualified to operate a vehicle.
Most people purchase vehicles to drive from point A to point B, sometimes with passengers. It's not that complicated.
