Strange how he spends zero time discussing the UI which he actually used: the voice control, which i treat as the primary interface to my car and my house.
I get that he really wants a button as a guest in a car. But as an owner of a car, I would loathe 10 buttons I never want to push.
As a counterpoint, I loathe voice control, I just want to push a button.
I'm not saying this just as an counterpoint-for-the-sake-of-arguing, I don't use voice control on anything - phone, TV, home automation, car, etc.
I know many people like it, and that's great, but I do not think at this point it has eclipsed hard buttons in things like vehicles where it should be considered the primary interaction method.
Voice control tech is still very patchy, especially if you have an accent or a speech defect, or if it is not capable of handling colloquialisms or you calling a feature by a different name as intended. All of these things are common enough in practice, and the last thing I need when I am driving is to have to bark a command thrice to get what I need activated, and then bark more commands to undo whatever the car actually did by misunderstanding my commands.
