For all the anti-distraction people: Why is the Navdy HUD so much more dangerous than the already existing stuff in your car? At least when you are looking at Navdy you are still basically looking through the windshield. When I look at my radio or speedometer on my current vehicle, the windshield relegated to peripheral vision which is useless in this case as you get no depth information from the peripheral. With Navdy, you still should be able to see something coming at you. It seems far superior to the current HUDs in cars.
Illusion of safety. It's the distraction that really matters. Of course looking down introduces a risk factor, but studies have shown that it's the distraction itself that is dangerous. The HUD will create the illusion that it's ok to do certain things -- more often probably too -- while driving, now that you don't have to look down to do them.
One could also argue that when you have to look down to do something distracting, at least you are being reminded -- by taking your eyes off the road -- that the thing you're doing is distracting and you should probably pay attention to the road.
