No but it converts the action into a multi-step process. A button is a single-step process. Multi-step is fine for infrequent configuration-type actions that happen when you are not actively driving but are a distraction while driving.

It’s also a multistep process with a touch screen: 1) find the button on the screen 2) lean over to reach it 3) touch it and look at it while doing so to confirm you did it right.

In a clickwheel car the wheel moves the focus rect. You twist it blindly to approximately the right spot. Then you look at the screen and adjust one or two clicks and press to confirm. You won’t trigger the wrong action by accident and the focus rect makes the operation async: you don’t have to look while you turn the wheel, you can look at the screen when it suits you.
