The standards for evidince, processes for enforcement and court side of things are not set up for cheap enforcement of "that clearly ain't right" behavior. They're set up for revenue enforcement of easy to prove but not necessarily bad in abstract offenses.

Police can't substantially increase enforcement overall because that would just cause bad political optics, say nothing of stops that needlessly escalate to being newsworthy in a bad way. They'd necessarily issue a hundred petty bullshit tickets for every deserved ticket for legitimately bad behavior. It just wouldn't work. It would be like trying to plow a field with the ripper on the back of a bulldozer. It kinda looks similar but it's wrong for the job.

And all of this is based on the assumption that we're trying to enforce things that the broad public agrees need strict enforcement, not whatever the original comment wants.
