Making car-pedestrian collisions safe is a ridiculous idea failed to doom from the start. Cars are big and hard, people are small and squishy.

My quite large awd minivan that can tow 3500 lbs and fit a massive amount in the back has a hood that slopes down quickly to about a waist height. God forbid if I hit someone, they would clearly be scooped up onto the hood, which might sound bad but literally every single new pickup (with basically the same specs as my minivan on paper except with less capable AWD because of no weight in the back and a bed that doesn't come with a cover like mine did) is basically designed to try to hit a pedestrian in the shoulders and head and smash them down under the vehicle. This isn't a hypothetical safety thing, pedestrian fatalities are raising at an alarming rate because it has become cool for insecure men to drive around pickups that are optimized to kill a pedestrian in an accidental crash. Also, the rear cab seats of these pickups are extremely dangerous in a crash (there isnt any space to cushion collision) which is dark given that I always see losers driving around their whole family in these monstrosities treating it like a family vehicle.

I agree though that kicking cars out of places that pedestrians are in and valuing pedestrian use of public ways over car use especially in urban areas is ultimately the best solution.
