I wouldn't wear them when I'm walking in the woods or hanging out at home. Having 'incoming car warning', or waypoint nav when I'm biking/running? That would be great!
Garmin has offered this for years. As a plus, the Varia taillight has a radar, so you don’t have to wear your pervert glasses on the back of your helmet to alert for incoming cars.
Yeah, what I was thinking—you don't need something strapped on your face to do these things.
I personally prefer good old situational awareness
As long as it's achieved in the manner that you approve of, of course.
