I find it interesting that HUDs and other augmented reality devices are being implemented for soldiers on the battlefield, aircraft, cars, etc. but somehow when that augmented reality display combines wearable and car it becomes as dangerous as a dumb*** taking his eyes of the road to text on his mobile. I would assert that given the same kinds technology are being implemented with goals of improving outcomes on the battlefield, provide safer air travel, remove the need take your eyes of the road to look down at the dashboard in cars, etc. that the burden of proof rests with the regulators not the other way around. Show me evidence that eating a cheeseburger, adjusting the radio, smoking a cigarette, putting on makeup, turning around to yell at your brats in the back seat, or any other among countless unregulated activities are less dangerous than wearing an augmented reality display while driving. The conspiracy theorist in me wonders if this has more to do with Google Glass' ability to provide for easy monitoring of law enforcement.
