Fighter jocks and attack guys have had something like this for awhile now and some helicopter bubbas are getting them too. I tried one out a few years ago that had an internal battery for when I disconnected from the helicopter’s power/intercom to dismount and retrieve a fallen troop. Our helmets were open face with the visor pulled down and worked pretty well for telling us the helicopter’s info like airspeed, altitude direction and so on.
For motorcycle riding with my full face helmet, I have to look down and away from the direction I am going to see the speedo. If I rode a R3R I know the gauges would be higher and not an issue. I have found that when I am in the mountains or other twisty roads, that riding by the seat of my pants (I don’t look down in these cases) is almost unforgiving on the R3T; almost. If I had the relevant information in my visor, I think I would be a little safer when I am pushing the limits of machine, road and myself. I agree that it needs a longer life though or maybe connected to the bikes power source. So, I’m for it.
