Joe mode is helpful, but I still find my music interrupted far too often. For example, pulling into or out of the garage the car constantly dings to tell me how close I am to the wall. Since I don't go flying into my garage, this takes a bit of time and the music constantly fluctuates in the process. Also, every time I engage or disengage autopilot my music is partially muted. These annoy me.
I would like Joe Mode++, where only the most urgent safety notifications cause my music to reduce in volume.
