My rule of thumb is if it's on the center console I shouldn't be messing with it when the car is in motion. If I'm supposed to mess with it while moving it's on the wheel or immediately around it.
And tbh between my car with a zillion buttons I shouldn't be pressing while driving and a small screen and the car where most of those functions I shouldn't mess with while driving are on the screen I prefer the screen. Far bigger screen to quickly glance at the maps when driving instead of a smaller one that's harder to see. Less space to actually see the media collection when I'm stopped and can safely navigate it.
That's on the steering wheel on practically every car I've had for over 20 years of model years.
You probably shouldn't be flipping between audio sources while driving. But even then, I've had change audio source as an option on steering wheels before. Generally, you shouldn't be fiddling with the radio when the vehicle is moving, you should be driving. Keep your hands on the wheel and your eyes on the road, not on the stereo in the center console.
FWIW, in pretty much every car I've had since a 2012 model year I've been able to press a button on the wheel and say "tune to am 1510" and it'll tune that without having to take my hands or eyes off the wheel. Far preferrable than trying to look over at the radio to find the AM button again and figure out which knob is the tuning dial and then look to see I'm tuning to the right station.
Every time I try to talk to the voice assistant its the most horrible driving experience. It hijacks everything, and definitely sets me to where I have to pull over, or just stop trying to talk to it to get anything done. It does not understand me whatsoever.
