CarPlay is also a contract between mobile devs and automakers. It allows for things like displaying "current playing" on the dash, media buttons on the steering wheel that control apps, and turn by turn directions show on dash and HUD. A screen cast may be able to do this but not in a consistent dependable way.
Also no one is mentioning that maybe we should not encourage users to use 1000s of apps in their car? It would be irresponsible to easily allow users to watch youtube while driving. Keeping the set of apps usable through the car is a responsibility in automobiles that are already becoming too distracting as is.
