Absolutely. Having things like the fuel gauge & speedometer within my field of view as I'm driving means I don't have to look down / away from the road to check.
HUDs are something I thought would be gimmicky but it’s actually really useful. Eg. for navigation it can show you where/when your next turn is without having to take your eyes off the road. It works really well in my experience.
Would I give up my car free lifestyle for windshield augmented reality that makes it look like I've got Mad Max as a crucified hood ornament? No, but it's an excellent try.
Seems like a much more expensive method compared to a simple projector. Also, a screen would still display a HUD. A HUD isn't a technology, it's just a means of displaying information.
