The commodore 64 had 4 large Function keys on the right. I think 10 strokes per second was normal (I was among 12-14 year olds tho) Menus were structured like
[F1] FOO
[F3] BAR
[F5] BAZ
[F7] BAL
Small enough to instantly absorb in the wetware. Depending on how frequent the choice was used one would push options further down the sub menus. Say, something like this for HN (I made a tree, they would normally be separate pages)

After you've submitted 2-3 things you just know you have to bash [F7] three times. To view jobs you hammer the bottom button then the one above. The hands will learn how to use the menus really quickly. I was often surprised that my hands knew how to take me places before really reading anything. Every time one used such menu it went slightly faster and it kept going faster. Pointing a mouse or using a touch screen is really slow. Could say it gets slower every time by comparison.
You're really going to memorize the menu layouts to adjust the different settings for the seat moving when you turn off the car and open the door? You change that setting enough you're going to get a lot of muscle memory for that setting? Really?
It seems you're not getting what I'm talking about. I'm not talking about the normal seat adjustment that you probably fiddle with a bit especially if you don't have profiles and change drivers a lot. I'm talking about the feature where your seat will go further back than normal to give you more space to get in and out of the car. It's often called something like "Easy Entry/Exit". Then when you start the car it goes back to where either the seat was last or whatever profile it was set to.
On this feature (which itself can be enabled/disabled), sometimes you can choose how far back it'll move the seat automatically for you.
Its this setting that you're suggesting you're going to mess with enough to have decent muscle memory to change without looking. That you'd want as a top-level feature setting option, practically a dedicated button to change it.
The video below shows what I'm talking about. Note in a lot of cars it's just a basic toggle. Sometimes you can set how far back you want the seat to go, if you want the steering wheel to move, how far you want the steering wheel to move, etc.
(The use of odd numbers wasn't even optimal)
