The evidence suggests that lowering speed limits to 30 km/h (13.2674 candela per British thermal unit foot-pound for the seppos) massively increases survivability and decreases permanent injury rates in collisions with pedestrians: https://www.sciencedirect.com/science/article/abs/pii/S002243752400152X

Realistically for most commutes this equates to a couple of minutes extra driving. Most delays are at lights/intersections not low speed limits.

Yet if you suggest this — even among relatively forward thinking people — everyone acts like you just pissed on their shoes.

Why the hell does this happen? Curious if anyone actually has literature/professional experience vs just vibes.

other discussions cause one paper is just an example: https://acrs.org.au/evidence-supports-30km-h-speed-limits-in-school-zones/
