Great chart and SF downtown has a denser deep blue color; always suspected that is a more risky place for pedestrian.
Without some way to control for density of cars/pedestrians, this chart is quite useless.
What's with all the 99 year old deaths in NYC? Bad data?
I saw a billboard last time I drove through NYC, explaining why the speed limit is 35 rather than 45. It basically said that if a car hits a pedestrian going 35, the pedestrian will probably live, but if a car hits a pedestrian going 45, the pedestrian will probably die.
