Android auto, what is it good for?

[DAS]

For me just podcasts.
The Megane is a Google car so it's map integration with added car info, like charge state at end of journey is superior to the phones maps.
I can't get plugshare to work in the car, `an error has occurred.... So just podcasts for me.

Not good for playing music from USB sticks, that's for sure
