The title suggests that Google is fighting against distracted driving laws, but when you read TFA, it sounds like they are really fighting laws that ban Glass-like devices which, depending on your point of view, might not be the same thing.
When I'm using my phone to navigate in the car, I have to glance at the phone occasionally. If I had Glass active and it was showing some of the same things, I wouldn't need to look away from the road and (in theory) could be less distracted. IMHO, I would think a blanket ban on the device is premature at this point. If Glass is released to the public and the data shows that it causes problems, the it will be time to start the discussion.
