You say that as though somehow using a phone is an integral part of driving. Guess what. A couple of decades ago very few people had phones and they drove fine without them. What is so damn hard about not chatting away or doing something else while directing a multi-ton vehicle? If you really need to talk, pull over, stop the vehicle, and carry on with your conversation. You say it as though we can't easily pull over. People pull over all the time on the highway for emergencies such as flat tires. You don't need special flat tire changing areas to stop your vehicle. If the conversation is not important enough for you to do that, then wait and talk later.
