I mean you're looking at less than $100 in raw parts for GPS + Arduino + HD Camera + display controller/OSD. Not sure about the HUD part but I believe it's just a projection on a small piece of glass, probably also less than $100 in parts by itself not to mention alternative hardware implementations that might be cheaper. Add $300 for a decent helmet, wire it up and you're done.
Yep, and what you'll have when you finish is a kludged-up helmet that does nothing unless you manage to source the hard-to-obtain Arduino Motorcycle Helmet Edition that does all of the navigation, phone interface, etc. You're also assuming you'll get it completely right the first time. which you won't, because nobody does. Price in a few helmets and at least two sets of hardware and you're already into the same price as a finished AR1. Don't forget the value of your time to do all of the hardware integration and write all of that nifty software.
More fun: Your modifications will invalidate any safety certifications the helmet you started with, making it not legal for road use almost everywhere. As a free bonus, you'll get to ride around with a niggling question in the back of your head about whether or not the helmet will do its job properly during a crash.
Personally I think I would find the HUD hardware incredibly distracting. Not the HUD itself mind you, but the stalk that sticks up in front of your eye.
If the photos I've seen reflect what will be produced, it doesn't stick up any further than the breath guard, is in a location where vision is not all that important and isn't any larger than Legal Speeding's H.A.R.D., which is often installed in the same spot.
