There is a few good posts making fun of it but beware of the many "uhhh ackshully" nerds trying to explain how no one could possibly know that it's a legal crosswalk when painted like that so it's good, actually it got painted over https://twitter.com/anxious_e/status/1410986599848890373
There's literally tons of other cities with permanent rainbow crosswalks. I know a neighborhood in Atlanta that has them. Never heard of anything accident related being caused by them
