Obviously a car doesn't need to do any of these things, especially in the age of the smartphone. A good tradeoff might be: 1. Physical controls for everything 2. A separate mini tablet screen for an advanced CarPlay-like dock that connects to your phone. Ideally the physical controls would do everything on the screen as well, so the advanced functions can be accessible while driving (if you absolutely need something there).
