"At least with glass you can keep your eyes facing the road while gathering information"

But can you keep attending to the road? Fighter pilots can, but they take a lot of training, lots of them don't make it through training, and their display doesn't show 'I am contacting you on behalf of my deceased Nigerian aunt" messages.

For mere mortals, I think it may be safer to have separate gaze directions for 'looking at the road' and 'looking at my cellphone's screen', if that screen shows data unrelated to the driving task.
