there isn't ANYTHING stopping anyone form making a small LED hud for a helmet now for personal use.
my beef is the 5 year shelf life on helmets. thats $400 a year for this helmet. I don't see the value.
Speed I can understand in a helmet. RPM and gear though, might be too much info really. its one thing to have them available to look at on the cluster, but another one altogether to have live in front of your face.
I got to test a wearable computer for a while. (pre Google glass) and honestly it made things just way too hectic. as cool as the idea was, it was just too much to process.
I'm all for tech, and I'd really like to see this happen, but the timing is premature, and the price is too high.
