I am not sure how it could be much more intuitive, at least from a touch screen perspective. It’s just a touch interface with an app drawer, nothing much more to it than that. However, if it wasn’t a touch screen I could believe it not being very nice to use, as I have a friend that has an Audi that does CarPlay but the screen isn’t touch, so he had to use physical buttons to use the interface. THAT is definitely not good.
As for the apps, I use Signal, WhatsApp, Messages, Spotify, YT Music, Waze, and Google Maps and they all support AA, so at least for my purposes it does what I need from a car apps interface standpoint.
If you’re talking an Android tablet/headunit, separate from Android Auto, that makes sense… But Android Auto is essentially a simplified interface for specific apps installed on your phone, and is generally quicker and safer than using the phone interface. No one here is arguing for a separate android console interface, so I’m not sure we’re talking about the same things. The whole point of Android Auto is to take a separate interface and OS out of the equation and to allow you to use your phone as the brain.
