I think the fact that nobody is stopping them for doing 90mph down city streets or blasting through red lights without a second thought is doing a lot more to tell them their behavior is ok. Serious question: how many of the people we're discussing do you really think are aware of a bill that came out of Philly City council and what it says? Do you think the folks racing Dodge Chargers on Delaware Ave were waiting for an all clear from city council? Reckless driving behavior was already present. It exploded when the police stopped pulling them over for it, which was after the bill was passed, because the police didn't like the bill.

We're kind of at an impasse at this point, I think, because we don't have the kind of data analysis necessary to figure out the nuances of causation. The one thing I keep coming back to is that the police ARE the only ones who can enforce existing traffic law and they are NOT doing it. If that changed, it stands to reason the behavior would be reduced.
