My understanding is that in some specific instances the Head Unit will
indeed need to talk to the vehicle. I'm not pointing to safety critical
systems here however, but pointing out in a rather general way that the Qt
API is likely way to abstracted from the vehicle's controls to be enough to
fulfill requirements, including OEM and Tier 1 requirements. I worry that
limiting MeeGo IVI to only Qt APIs will likely make it not suitable for a
production Head Unit which makes the entire MeeGo IVI enterprise less
viable.

Why would people invest time and energy in something that wasn't going to be
a product?
