How do you see what the joystick is pointing at without looking at the screen it’s controlling.
Radio volume, climate controls, and drive/transmission controls are all necessary for safe operation and should be able to be used without taking eyes off the road if needed. There should be federal mandates to keep those controls off of gaze required touch screens. (I’m looking at you VW, of which I own 3 classic examples, but would never consider a current gen one).
I know this wasn’t the main point of your comment, but to be grammatically correct, it would be “the maths math.”
Plural verbs go with their plural noun subject and don’t need the s:
And like you said, maths being short for mathematics means it’s plural.
