Not op, but in my experience the root cause is too many vehicles, which leads to horrible rush hour traffic. So know traffic management is overloaded, and so people push into a lane/run a red/etc. I don't know how much time it saves, or if it just gives people a feeling that they're getting there quicker. Meanwhile police are also overloaded, so don't issue traffic fines for minor infractions, which normalizes it. So then drivers get more brazen and pedestrians are likely to think twice about walking, and it's a bit of a self-fulfilling cycle at that point.
