I'm with you guys......I've seen some sort of rearward camera/visor hud somewhere, but may have been a prototype? Not searched for them, so I dont know what's available. I agree with the concept's market, safety is always needing addressed.....but this is poor application. Who would want their helmet's integrity compromised just to see behind them when the mirrors on the bike haven't been improved on since mirrors became a standard? I mean, don't their necks work to look both ways?
