I'm sure he drives stick as well because offloading cognitive function to an ECU changing gears for him would also be against his religious beliefs.
This kind of automation takes the execution away from you, not the decision, and even that execution only concerns you. You wanted to shift into a higher gear, the car's computer does it for you. The result is what you wanted. A fully autonomous car that decides everything for you would be a better example.
If you let an AI grade an exam then a big part of what comes next is a decision that you didn't take or validate. You didn't remove yourself just from the execution, you removed yourself from the responsibility and cognitive effort to take the decision, and from the accountability for that decision.
If you can simplify and call every button press "just the computer doing things", then someone else can exaggerate and say a fully autonomous drone hunting humans is the same, business as usual, computers doing things.
that's me
Outside of America, most people drive cars with a manual gearbox.
