This is a big part of the problem.

There is little fear of penalty if a driver decides to be a turd and run lights or act super aggressively, speed, swerve, not allow pedestrians to cross, weave in and out of traffic, do donuts in a random intersection, close down bridges so they can showboat.

Let's get back to setting up random traffic stops. Ticket the general idiots, bring along 10 NYPD tow trucks and confiscate all the ridiculous violators. Then auction off the cars, minus the illegal junk, and use that for more police training and traffic enforcement.
