As others have said, Glass + driving will lead to increased accidents and will likely be banned in the same manner as texting while driving. A recent study by AAA showed that voice-to-text messaging is more distracting than making calls with a cell phone. For the average person, multitasking while driving will almost always be more dangerous. Pilot HUDs are not comparable, because they are focused on flying, the task at hand, and pilots are highly trained in using them. I doubt that users will restrict themselves to map apps while driving.
