While their conclusion is probably correct, I would have liked to seen the number of fatalities normalized by population, miles driven, number of pedestrian increase, speed limit change etc
So maybe deaths per mile would be similar, but we’ve pushed people further and further so they have to drive more miles, increasing the deaths due to poor design.
Building society in a way that we increase deaths due to poor planning, like making driving the only option for the majority of people, gets hidden by statistics like “per mile” or even speed limit changes, which are also more necessary as people need to go further to get to their daily activities, rather than everything being within a short walk or safe bike ride
