I believe most jurisdictions in the US have largely the same framework. At least everywhere I've lived all street corners were implicit pedestrian crossings with a legal requirement (often blatantly ignored) that vehicles yield. Similarly jaywalking is a misdemeanor and only applies within a certain distance of a crossing.

The only situations where it's enforced (from what I've seen so obviously biased) is major highways, city streets with dense traffic and a marked crossing within half a block, and when they want to search someone for contraband. In the latter case it's just an excuse to stop and harass you in the hopes they will manage to generate sufficient articulable suspicion to justify a search.
