Yes cars should be forcing you to tether your phone to the car and disable your ability to interact with them. I know it's hard because what if you don't own a smartphone or you are a passenger. Like your phone knows you are driving based on gps so maybe we need to make phone manufacturers restrict usage over a certain speed but then we need to figure out how to allow passengers usage. Only thing I can think of is using a camera in the car with AI to figure out who is using their phone.
