What's stopping you from using Waze in a Tesla? It has worked great for me in the past, and I assume would now as well.

This is like people who think that by using one browser you must "switch" and get rid of the others... no.

But the latest updates of the Tesla stuff are great so I can't remember the last time I used Waze.

CarPlay, I can't speak to, but I find the built-in music features just fine.
