I want this problem fixed, too. Driving in New Haven is a joke, people blatantly disregard the traffic laws here because they know that no one will do anything about it. The police can't really do much about it, because the higher ups in the city and the pd believe that traffic enforcement is a waste of time and resources. They don't seem to understand that enforcing traffic laws and pulling people over is a good way to get guns and drugs off the streets, or that it is a good way for the city to fill it's coffers from the money garnered from traffic tickets.
For statistics, the city should look at surrounding areas. East and West Haven may get slammed for being too willing to pull everyone and everything over, but about 1/3 of their traffic stops result in citations or arrests- getting drunk drivers off the road is just great no matter where or when it happens.
I have been saying this for years, but nothing will ever change in New Haven until we get some new people in office.
