Zac Hall, 9to5Mac:

Apple upgraded CarPlay in iOS 12 with support for third-party navigation apps including Google Maps and Waze, allowing drivers to use alternatives to Apple Maps for the first time. CarPlay has an even bigger update in iOS 13 with the introduction of Dashboard, new apps, and updates to existing apps.

This is a pretty solid rethinking of the CarPlay interface. Yet another example of Apple firing on all cylinders.
