Lol, but I get that. A proper affordable heads up display will add so much more value to my life. I ride motorcycles and that is where it can be really useful. A Kickstarter tried ot a while ago with a helmet,but that flopped badly. A pair of glasses that will fit in my helmet, beaming useful info to my eyeballs could be lifesaving.
I had a long rural night ride a while back and it was bloody tricky navigating with the mounted phone. Not out of choice, more of a needs must scenario. The Gaiman map app was very useful in indicating the road ahead, bit the split attention needed was insane.
