Voice control is much much much worse than touch screens. You have to try 10-20 times to spell out a command before it maybe does want you want, and that is if you're incredibly lucky
That's weird. I never ever had trouble with voice menus on the phone, and I bet that phone lines are worse than what you can have in a car, and the processing resources spent on recognition should not be large.
Mileage varies a lot on this one. I have an Android Automotive car (not to be confused with Android Auto) and “Hey Google” is basically flawless for changing car settings while driving.

European agencies noticed and started requiring physical dedicated switches for certain most important functions to get a full safety rating.
Car makers also gradually revert to physical switches, and also push voice control for certain functions.
