I also don't get all these people clammoring for CarPlay.
Previous car was BMW where its iDrive was widely recognized as best infotainment system in the business. To enter a POI, or god forbid, an address, took about endless taps (Home, Nav, Search, Country, City, Zip, Street Name, Intersection, etc). On Tesla it's direct search with auto-complete, engine seems identical to google, traffic-based routing, etc.
Media navigation is also incomparable. It's like using Windows CE on a phone vs todays Android/iOS.
On other cars ive tried, CarPlay and Android Apple were an improvement on the factory system, but even then the graphics and scaling were pretty terrible.
Don't understand what people find lacking with Tesla's UI, but everyone has an opinion.
