I
definitely see the appeal.
A vastly larger screen where you don't have to crane your neck down to read the news? That sounds amazing for my daily commute, and so much healthier for my neck and shoulders.
And visible directions while cycling would be amazing, when it's unsafe to glance at your phone. (Audio directions aren't nearly as good, and wearing headphones/earbuds while cycling is illegal in a lot of places as well.) A heads-up display in your car should be safer too than looking down at the screen.
And if people are having video calls while walking, that doesn't seem any goofier or creepier from audio calls with earbuds, where it already looks like somebody talking to nobody.
