Imagine that you can now wear it while driving, and there's an app that will show you everything about the route and your cars' statistics right in front of your eyes
Unless you're in one of Google's Self Driving Cars this sounds like a recipe for disaster. If these things take off I'm pretty sure wearing them while driving will be pretty quickly outlawed.
The display in Glass is incredibly unobtrusive. Glancing at a direction arrow (for maps) is no more distracting than glancing at the speedometer--it's less distance for the eye to cover, and the displayed images are ruthlessly simplified so that absorbing them is almost subconscious.
I think the danger comes from people who get text messages while they're driving and want to look at a shared photo. That should be disabled while driving, which glass can make a pretty good guess at.
Why? Seriously wondering here. I don't see it any different than having wireless phone, navigation, radio, and the countless other things we already have in the cars. Main difference is this would be right in front of us meaning we don't have to take our eyes off the road to change the radio station, check the nav or answer that call.
