It completely stops everything else playing. I think they need multiple microphones to do the signal separation (like Homepod and Google Home do) but I'm not sure if the car has multiple microphones inside (new Model S and X certainly do as they have active noise cancellation for outside noise).
I wonder whether I’m an outlier here. The engineering investment to make zero-disruption voice control seems relatively minuscule, at least compared to all the other big-league AI/ML they’re up to. I’d rather have that than… just about anything.
