Right, like auto makers would never put a phone style interface right into their cars, so that people could avoid "distracted driving" by hooking their phone up to their car and using the car's touch screen legally instead of the phone's. Only insane hobbyists would do that, as it combines the worse aspects of the requiring human touch and distraction to operate with the slow technology release cycle of auto manufacturers.
