Glass verbally reads you the text, you verbally reply to the text. Even if you glance at the screen, it's more like an overlay than a second place to look.

Comparatively, the center console of a car is drastically less safe to look at than a heads-up display like Google Glass. We seem to accept that center displays are largely safe to use (with some functions disabled while driving).

None of that means it is safe.
