F=mv^2 The problem is moreso speed, not mass, when discussing pedestrian fatalities. Better yet, protect pedestrians from getting hit in the first place with better street design for more walkable cities. There are tons of examples of protected bike lanes, pedestrian islands, and more frequent crosswalks with stiffer penalties for blowing through them, regardless of what the vehicle is.
