* In April 2014 San Francisco police issued 11,612 tickets for traffic violations. In April 2022 they issued 338. No, that's not a typo. It went from 11,612 to 338. (Some links here: https://twitter.com/hknightsf/status/1537100042623848448)
* NYC police issued 5,039 tickets during the third week of July 2022; they issued 19,126 during the same period in 2019. Unlike San Francisco, they haven't totally stopped writing tickets, but the numbers are down drastically. (Some info: https://nypost.com/2020/08/09/nypd-traffic-tickets-plummet-b...)
