I swear people here have no concept of what terrible walkers they are.. taking up the whole sidewalk, that _single_ guy walking up the left side when everyone else is coming the opposite way on the right, making all of them get out of the way, the people who just stop walking, turn around, and run into you.
It's really annoying, but I don't think you can just ad-hoc legislate it. We have tons of things that were made illegal in NYC and a tiny amount of the laws actually get enforced. As others have said, this can lead to laws only being enforced on people the police already want to harass, and everyone else doing it on a regular basis.
In addition, with our Vision Zero goals, there are so many other things to focus enforcement and government bandwidth on. Hundreds of people are still being killed by reckless drivers every year. If we can solve that, then we can focus on getting people to be less annoying when walking around.
The scale of it is like stopping on the freeway to take a photo of a billboard. It holds everyone up because you put yourself above the people around you. It's rude.
I really wish NYC would have something like this.
I don't get it either. Either stop (and get out of the way) to look at your phone or walk. Don't walk an one-third pace. It's pointless and annoying.
Much like texting while driving I think the majority of offenders believe they can look at their phone without it impacting what they're doing. it's alsmot universally wrong.
