Honda has been shipping Android powered entertainment systems with direct access to the CAN bus (which may even include vehicle control, based on geohot's work) for several years now. Just as on phones, as long as this using being used for timing critical operations like an ECU and doesn't have any sort of remote network access it doesn't seem to be a major source of issues.
He could be right - I was operating under an assumption that it's the same CAN bus access they're using, it's entirely possible it's only an isolated segment.
I did not confirm this, purely an assumption on my part as it does appear to have access to HVAC, lock settings, as well as fuel information which makes me suspect it's not so isolated.
