I think the applications of AR glasses have always been fairly compelling; anything we currently have to do by staring at a phone screen, we could do without having to look away from the real world. The main problem I see - and it's a real one - is that they're so visible, so obviously techy, that few would dare to be one of those early adopters and actually walk around town with cybergoggles on.

But what if they were driving gear? There's a lot of information we want access to when we're driving - speed, maybe a map, and ideally a view of blind spots. Practically speaking, the easiest way to make sure we can see all that without having to look away to study a screen is to physically strap that stuff to your face.

So they're attractive for their features, but that's not the real reason I think this might be where AR glasses finally get a mainstream foothold. The real reason is that we feel invisible in cars, so the uncool factor is not such a big deal. People text while driving, people pick their nose ... heck, I saw someone reading a book with a coffee in their hand once. And look at what cyclists are comfortable wearing as part of the bike experience - it can't be a coincidence that some of the biggest adopters of AR glasses are cyclists.

So maybe this is it, maybe AR glasses will finally sneak in the back door in an environment where we're less aware of people watching us. With "cool" brands like BMW and Jaguar throwing money at it, maybe this is where it starts to cross into the mainstream?
