They sandbox many of the different systems. Carmakers won't cede deeper control to Android Auto or Carplay because they want to hold on to being the main user interface. There's also safety, security, and data-sharing issues at play.

Fair enough, I would be OK with having to run a Ford app through Android Auto to access that functionality on a Ford.

I just want the best of both worlds .. trying to hold onto being the main user interface feels short sighted. I'm not going to NOT buy your vehicle because I can use Android Auto vs your custom UI, so having both available shouldn't be a negative to the manufacturer.
