Got to test car play this morning and I think its off to a good start. The new layout while in a phone call looks much better. The dual app feature is currently more of a gimmick, but an acceptable one. By this I mean when you hit the dual app button you see the map on the left and your audio player in the lower right. The ONLY map it shows currently in Dual app mode is Apple Maps. If you want to use other maps such as Google Maps or Waze then you must use them in full screen mode. Hopefully this limitation is currently just because those apps have not been updated to iOS 13. I notice in WAZE since my phone is in Dark Mode, that on screen on Carplay that it is also in Dark mode. (I hope they fix this, before it would use the light sensors in my car to automatically switch between light and dark mode. Just dark mode on the carplay screen is hard to read during the bright daytime. The audio player in the lower right seems to be the same player no matter what audio service you are using, I don't see a real issue with that. The controls it offers you are 30 second skip back, Play/Pause and Skip Forward 30 seconds. If you want to change the channel you need to go back to full screen mode. What I would like to see is the ability to change the provider for maps in dual app mode as I like to see traffic / police / hazard info from Waze. In addition I would like to see Digital Radio Presets so I can just click on the radio preset I want and it opens up the proper app and plays the channel you select. Press the Howard Stern Preset and it opens SiriusXM app and plays the Stern Channel, Press the American Top 40 preset and it opens the AT 40 station from iHeartRadio, Press my favorite station from TuneIn and it opens tunein and plays its... etc. I could see a bar across the top of the screen with 5 or 6 presets, maybe even hold more presets by scrolling back and forth from left to right. This would be a HUGE safety improvement as now you wouldn't need to go to the Carplay home screen, then find and go into the app, then find the station you want to listen to and then click on it.
