The wireless dongles that I've seen advertised only work with certain cars.
Even as more and more cars offer this most people won't buy a new car just to do wireless CarPlay. I suspect this is a very dangerous area for Apple in going completely portless. Maybe the next version of MagSafe will include a connection to do CarPlay via a USB-A connection.
Maybe keep a second iPhone to do most CarPlay functions and use the Bluetooth to do phone calls - who knows.
