It's so frustrating. These things are trivially solved. There's basically a 50/50 shot, every time the light cycles, that someone will illegally take a right on red on the street outside my house. All you need is a single cop sitting there and watching. Or just one camera! Argh.
But people speeding, driving aggressively, driving anti-socially (by trying to speed past lines and cut in at the front), running lights and stops... this could be squashed forever, saving lives and ultimately making life more pleasant for everyone.
