Speed limits in pedestrian-heavy urban areas and children-heavy residential areas absolutely have to be no more than 25mph. The difference in survivability stats for pedestrians struck at 25 vs 35 are stark. What we need are narrower roads, pedestrian islands at intersections, and harsh enforcement. On highways, it doesn't matter. Survivability between 65 and 75 or even 85 is not that much different. You're going to have a really bad day regardless of speed. Far more important is longer ramps, higher vehicle inspection standards, and higher licensing standards. We also need to get long-haul shipping off the roads and back on the rails.
