I agree with this. Voice control fitted to cars is pretty terrible still. It interrupts playback, takes a long time to resolve an input and takes even longer to repeat it back to you before doing it. Siri makes this a little bit better, but she's not been given access to the AC APIs of my car.

Buttons are the way. Or those cool switches from fighter jets... I'd like to see those in a car.

Alternatives are important for accessibility, but I don't agree that they need to be available to all drivers at all times. The idea of going back to panels of analog controls that I have to reach for and memorize the positions of just isn't appealing. They break, the paint fades, they chip. CUIs are easier and safer in general.
