My new work routine finds me once again on the roadways of New Jersey, roads that I'm quite familiar with, and have traveled most of my driving life. I've done enough traveling around the country to know that bad driving is a national affliction, but in the case of my home state, aggressive driving seems to have always been an epidemic.
(After living and driving in the San Francisco Bay Area for almost 2 years, I can tell you that drivers there may carelessly run a red light, they may even hit you or kill you, but it will be because they are dreamily contemplating their next move, or the alignment of their chakras, less because they are chomping at the bit to get to the office to close a deal and otherwise roll around in 3-letter business acronyms.)
Fortunately, the very congested nature of New York City traffic dictates that no one gets too far, or moves too fast, in a single clip. This likely diminishes the number of road fatalities that might otherwise occur; though anyone who reads the paper knows that pedestrians are routinely mowed down in NYC, often with little or no punitive action directed at the driver.
There is certainly a "style" to Northeastern US and NJ driving, an often maniacally aggressive, thoughtless tear ever forward, fueled no doubt by coffee, 60-hour work weeks, hunger, sexual frustration, inebriation and other maladies, none peculiar to, but somehow exacerbated by living and working in this most densely populated, frustrated little second banana of a state.
The statistics reflect the aggression, too. According to a nifty little pamphlet produced by the state, "...more than half of NJ’s drivers are angry when they’re behind the wheel. Almost half, the data show, are likely to try to "punish" other drivers. In 2003 in NJ, this attitude, combined with the above-mentioned driving behaviors, resulted in more than 68,000 vehicles being involved in crashes, an 8% increase from 2001. These crashes resulted in approximately 200 fatalities and 34,000 injuries." Download the pamphlet here [pdf]; then take the damning "Are You An Aggressive Driver?" quiz.
