I live in Boston and drive every day still. This is anecdotal - but I've seen the same amount of bad driving as ever (largely around merging, roundabouts, and turn signal usage) but now it's at a significantly higher speed because on I-95 and I-93 you can easily hit 85 mph instead of the customary 45 mph the whole way during rush hour.

I don't have any data, but I imagine that explains the similar serious accident rate.
