I'd love to be wrong, but it appears he has passed. The death record matched up to about a week or two after he entered hospital.
My team is continuing his Android Auto work by starting the OpenHU project. We've set up a $10,000 bounty - as Google just broke his app over there with changes to GMS: http://console.com.co/openhu
Saw people asking about this, felt I should share over here on Mike's other projects.
