Care to show regions where it was implemented in l.a. and fatalities in that regions? I just really doubt that speed bumps, artificial turns, increasing the turn angle, adapting semaphores to be before intersections and raised crosswalks have no effect. If there are no such regions that adapted these changes than vision zero stayed on paper. If such regions exist, I would be glad to research how fatalities changed after them
