A long while ago when they forst started talking about VR for the Mark II they said it was being programmed by a well known company in the market. It should be pretty good.

And I would believe that they suggest that particular mic because it not only has higher quality, but because it does the best job at singling out the voice in the noisy car environment. I don't think it's as complicated an "equation" as that. I know it's hard but it's mostly a factor of just singling out the voice from road noise and the music. This is something they've been counting on from the beginning, though, so they have been thinking about it.
