Normally when you need to wait at a crossing because it's red you take out your phone to waste some time. But you have to be quite anxious and look up if it's already green or not, otherwise you miss the green light.
But they help you out with that here in Korea by building in the traffic light into the curb. You're looking down on your phone and see the red line left and right of it. Once it changes to green you immediately are aware of it because it's in your field of view constantly.
Great invention!
I took the background picture just outside and put the stock picture hands with a phone on top of it so you can easier visualize it how it looks like in reality.
I don't know where you live, but here in Seoul nobody takes out their phone out at the traffic light because most of the people have it already in the hand while walking.
See this random video I just googled of a crosswalk in Gangnam: https://www.youtube.com/watch?v=OeadHl7ugmk
It seems it's not just in Asia, random London video shows also half of the people walking with phone in the hand: https://www.youtube.com/watch?v=vTxyohQ8jN0&t=11

Yup, everybody looking down at their pocket computers and fucking up their posture.
If you hold your phone in front of you you get bonus arm training
And impact protection.
Yeah, that's a problem.
