If things are loud in the cabin Alexa, through Muse, will answer the wrong question or send you to the wrong location.

If you say "Alexa" and you don't even know if it "heard" you, that's not a good thing

But if you are driving and the internet cuts in and out or switches to slower 4G, the music pauses while Muse-Alexa dithers, trying to make a connection
