Speed limits are arbitrary factors set in place that don’t make sense for the roads they’re on. They do nothing for safety, and often become a speed target. If you want to reduce speed of cars (which I agree is a good thing) the best way to do so is to make traveling above a certain speed feel dangerous to the driver. Chicanes, medians, and narrow lanes encourage that. Speed limits do not.
Speed limits are bs.
Simple answer is an increase in the number of cars and the number of pedestrians. If cars are 10x safer for pedestrians now, but there are 1000x more interactions…
