If it works like presented on those mockups it is useless.

And since we only see mockups I'm sure it doesn't work at all and is a scam.

I've tried to make a DIY hud for bicycle riding and it failed on two steps:

- you need enough brightness for it to be visible in full daylight, so the image was be tinny or the blue oled I've tried to use weren't bright enough

- my prototype worked well with a straight piece of glass and a plastic sheet Fresnel lens, but it wasn't good for actual use. For actual use you need to project out-of-focus image on a curved surface of bike glasses. I have no idea how to make it small, precise enough and cheap enough.

There are also miniature DLP projectors from TI, that I think would work but they were pretty expensive for a hobbyist to use.

Adding to sibling (with reference to the difficulty of producing good AR eyesets), the Epson Moverio do work very well. For the purpose of a HUD dashboard quick info - a few big characters (as opposed to, say, pages dense of text) - visibility against environmental light should almost always be given even without darkening "sunglasses" shades (you use the sequence "eyes, displays, shades" when you want to enhance the visibility of the display). So, confirmedly, in case of doubt, the technology is there already.

I don't know whether this particular product is a scam, but the Everysight Raptor is similar and it definitely works. Just because you couldn't figure it out doesn't mean it's impossible.
