I hear this a lot and it's surprising to me. We have three cars in our family (two with carplay and the Rivian) and carplay always feels like such a downgraded experience compared to that of the Rivian.
I have a plex server and use Prologue for audio books. What would my experience on Rivian be like? I am guessing I would have to connect to the infotainment system as a bluetooth speaker? Would I be able to easily skip forward/backward and see the current chapter?
I've been using car play for the better part of the past decade and don't know what it looks like in vehicles without it.
