Very frequently when there is a newsmaking incident in which a driver runs people over in some egregious fashion, it turns out that they got dozens of speed camera tickets per year. We know who these people are, we just don’t seem to have any motivation to actually do anything about it.
The city has published research on this, showing drivers who get 30+ speed camera tickets in a year are 50x as likely to be involved in crashes with serious injuries or death, but efforts to actually do something about their behavior are consistently stalled or watered down. Other research points to various causes, including backed up courts and decreased enforcement generally.
