> speed is one of the best predictors of pedestrian fatality and injury severity True, but a total red herring. Speed might be the main factor affecting severity of injury, but it's not the main factor affecting probability in a left-turn scenario. Remember left turns? It's what OP is about. Very few people are going the speed limit while turning left, and that would remain true even with lower limits. Visibility is the dominant factor here - around other vehicles, around the A-pillar, etc. The least severe accident is the one that doesn't happen. "Lower speed limits" is a great hobby horse, but not one that belongs here.
