Google glass is probably about as distracting as the various LED and console displays that already exist, including GPS ones

Current devices in the car cannot cover the centre of your view with some graphics. In most cases they're designed so that it's actually impossible. Can the same be guaranteed for Glass? I'm not even thinking about notifications and apps. What about a random app crash / reboot - how will that affect your visibility while driving?

If Google Glass crashes you just see whatever you would normally be looking at, the display is transparent.

If it crashes completely - yes. If there's a bug in the app - not necessarily.

"Current devices in the car cannot cover the centre of your view with some graphics."

Have you seen the Glass videos? The screen is on the top right of your view.

Ok, not the complete centre. The display I've seen in all videos takes up around 1/9th of the image - I'm not sure how it translates to normal field of view. But imagine that 1/9th of your view starts flickering - that would be rather annoying and noticeable, right?
