Right now I can't, for example, use CarPlay in my Mazda6. I'm stuck connecting to the system via bluetooth for very basic stuff, and then mostly using Mazda's horrible UI. I think other people have similar complaints about their carmaker's choice of infotainment system.
The point is, right now, whatever Ford or Mazda or Honda goes with, you're stuck using it or ripping out the entire system and replacing it with an aftermarket solution or grafting a second system on top of your dash. I would hope the future holds options like CarPlay for iOS users AND Android Auto (or whatever Google went with) for Android users, instead of an either/or situation. I'd prefer to choose the vehicle first and have various infotainment options available, then limit my purchasing choice to cars that happen to be compatible with my phone.
