Wireless Carplay uses Wifi (Bluetooth is used to establish the session, but doesn't have the bandwidth for screen mirroring). I have no doubt that Tesla's hardware is easily capable of handling both wired and wireless Carplay.
USB 2.0 datarate is plenty for Carplay.
It could be just another V9 app, or a pull-up window like the current music player. Other automakers run it in a windows as well, no problem.
That's because Apple didn't allow 3rd party navigation apps to support Carplay until recently. At least Tesla's navigation was always a viable alternative.
But they are not offering any good alternative for music and many other apps. Maybe sometime in the future there will be enough cars out there running the Tesla platform to make a rich app store economically viable for 3rd party developers. But in the present we keep fumbling around awkwardly with our phones while driving.
Yeah I knew Wi-Fi was used after Bluetooth, but regardless, only BMW supports that, there's gotta be a reason.
I agree they COULD make it work, but trust me, it'd be a signifcant UI rework. The current media player was designed around everything else, the split screen that exists, with CarPlay, they'd be forced into a much more vertical 8:3, 16:9, 5:3 type display which would make the rest of the UI (existing Nav, Car Menu, etc.) have to be reworked.
I agree on the Waze/CarPlay, I was blaming Apple solely on being slow. It took WAY too long for that to happen. As such, I've lost a lot of hope for Apple developing features out in a timely fashion, and with such limited third party apps, CarPlay just helps with some basic phone functions which most cars already do (not Tesla though).
My basic point which I should've summarized better is that outside of Waze, the rest of the apps are pretty non-worthwhile and the reason everyone wants CarPlay on Tesla is to basically allow most basic controls for music playing, text messages, etc. All of that is easily supported without CarPlay and wouldn't be as disjointed. I find my Cadillac and Volvo user experience for text messaging, etc. over BlueTooth to be better and more streamlined than CarPlay's, so I'd rather see Tesla do it right than CarPlay, my honest opinion. I agree entirely that they're not providing the alternatives, but I humbly do not think CarPlay is as good as developing the alternatives and frankly providing the most basic controls that exist in other cars (namely: iPod controls, text messaging, etc.). My 2011 Audi S4 did all of that perfectly fine.
