As someone who only had 20+ year old cars and motorcycles, I don't see what's CarPlay supposed to solve? All I need is a Bluetooth-capable radio and a phone holder to display the navigation, so I can listen to my music and focus on driving. Phone doesn't need to be touched unless changing destinations. Do people seriously need to be constantly entertained while driving?
Carplay isn't about entertainment for me. It's just a vastly superior and convenient way to view the same map you can see on your iPhone.
