CrossHelmet: A Smart Helmet ...

For that amount of money I'd expect a high intensity wifi LED in the back of the helmet connected to the brake light. Arguably adds more safety benefit than any 3 interior options combined that this helmet boasts.

Be careful what you ask for. Cagers like deer-in-the-headlights will say, "Whuzzzzz that shining on the back of this head ... ?" ... as their bumper strikes your rear wheel.

I personally would use the HUD over a bar mounted GPS phone (that always seems to get washed out by the sun) for daily traffic status. I don't care for music, but the inter-rider com could be a convenience bonus for long distance group rides. I think things like these will come cheaper in the next few years.
