That's exacerbated by ebikes. They're inexpensive, fast, and require virtually no physical effort, so people ride them everywhere. Before ebikes became so available, only very dedicated people would take them on the road, and everyone else treated them as toys.
If you look, I'll bet 9/10 of those breaking the laws are on an ebike. Look for thick down tube (connects handle to pedal), a visible battery pack, or absolutely no pedaling. A lot of those should probably be registered as scooters, which do require a license, because people frequently don't actually pedal on them and instead cruise at 20mph+ (>30kph).
People who ride regular bikes follow the law a lot more because they're actual enthusiasts, and thus care about the law. I'd guess most of those (say, 75%) follow the law most of the time, and innocently get lumped in with the people on ebikes.
