Possibly, but I would want a lot of limits on what it displays. It shouldn't display calendars, SMS, etc. because that's not pertinent to the task at hand, driving. I'm of the opinion that we have too many distractions while driving, even the hands free sorts of distractions are distractions. Humans perform more poorly on all tasks when they multitask, and when one of those tasks is life or death, I.E. piloting a 2 ton hunk of steel at 70 mph within 2 feet of other said hunks of steel, I would rather not have the distraction.
I could see it being useful for displaying the speedometer, fuel level, current speed limit, and driving directions but nothing else. Anything else is irrelevant to the driving task and therefore is a safety risk. Texting has absolutely NO place in driving period, whether through a HUD or on your phone. I hope the NTSB severely limits what these windshields can display.
