Connected Car
Making phone calls with Android Auto is something that many people take advantage of. If that's done, simply ask your display to call somebody by saying "Call" and then the name of the person. Perhaps the easiest method would be holding down the voice button on your steering wheel and then talking when you hear a beep. Another way would be the tried and true Google Assistant method of saying, "OK Google," and then uttering the command. All in all, it's a very nice feature to have with Android Auto and one you should be using.
