The folks over at The Bay Citizen created a snazzy tool for tracking bike accidents throughout the city. It tells you where troubled hot spots are and who was at fault for each incident (i.e. biker, car, pedestrian). Cool. And also kind of scary.

According TBC, “We analyzed every bike accident reported to the police in nearly two years — click any crash for full details. See where collisions happened, who was to blame and why. Find bike lanes for your commute and spot trouble zones.”
