Feature Description

When playing Something in Android Auto the last used playback speed is set as default.
It would bei helpful to have a possibility to switch between some default speeds (e.g. 50%, 100%, 120%, 150%, 200%). Because i use higher speeds for tech videos but want to have music in my car with 100% Speed.
