Just as an idea for a future beta release.
I suspect that many users would have a specific list which details phone calls to be made. Here in Australia, where you are fined for even touching your cell phone while driving, I am always trying to remember who I need call.
Being in the car for long periods of time I find that this is a great time to catch up on those calls.
As a suggestion, it would be extremely beneficial if I could select one list from Clear (ie my Calls list) that could display in Apple CarPlay. It would need no user interface on screen, however would be extremely safe way to remind me who I needed to call.
