Not very many accidents out in the middle of nowhere highways, although in my experience last holiday season there wasn't a single jabroni hogging the left lane. Granted, I usually drive everyone back at like 1 am, so mileage may vary.

You're absolutely right in the middle of the city though, and the number of people who get angry at you for not going 60 on a 40 mph blvd is way higher than it should be. I got honked at and a guy swerved around me just got both of us to get stuck at the same red. Those are the people who will certainly kill pedestrians.
