I prefer to think of what could be. In the case of cars glasses could identify where a part is or something and highlight it, almost like how it is done in video games with object selection. Cars are standard so it’s a matter of whether there is a payoff and how difficult it is to do. I imagine since CAD models for every part are created there is synergy there. No more “where does part X go?” - instead you can get highlighted areas potentially with facts and such. Parts could be embedded with small signal mechanisms or a QR code. There are many possibilities.
