I didn't see a comment yet about placing a loose object in front of your face. During a head-on collision you will eat that thing. Don't even put a box of matches on your dashboard. CD's become chainsaws. And this hunk of plastic?
Every year, loose objects inside cars during crashes cause hundreds of serious injuries and even deaths. In this paper, we describe findings from a study of 25 cars and drivers, examining the objects present in the car cabin, the reasons for them being there, and driver awareness of the potential dangers of these objects. With an average of 4.3 potentially dangerous loose objects in a car‟s cabin, our findings suggest that despite being generally aware of potential risks, considerations of convenience, easy access, and lack of in-the-moment awareness lead people to continue to place objects in dangerous locations in cars. Our study highlights opportunities for addressing this problem by tracking and reminding people about loose objects in cars.

Cars are regulated to travel below a certain speed. Phones are regulated to their use outside of a vehicle (when operated by a human), and kitchen knives are illegal to carry in public.
While the parent comment is a little melodramatic, there's still something to be said regarding the safety of usage in this product and its affect on other people.
HUDs are not bad. But Navdy keeps marketing their product as a text-while-driving aid. Not very smart.
Texting while driving is one of the most dangerous distractions primarily because of the interface: eyes off the road, hands off the wheel.
If Navdy can potentially reduce the danger of texting to a level comparable to that of, say, talking to passengers in your car, then I don't see how you can justifiably "realize" that it's a bad idea without seeing some statistics first.
