The biggest impact in residential areas is reducing both the frequency and the severity of crashes, when average speed drops. The best impacts are also had when combining with traffic calming measures that naturally slow people down to a lower speed - matching the design speed with the posted speed. That's a lot of what the motion talks about.
When you have the chance, watch the council archive of today's meeting - Churchill does a great job of explaining the science of all this. He's pretty interesting - he invented those yellow concrete things that are a cheap and easy way to create curb bulb outs - which have had a measurable impact in both reducing speed on corners, but also compliance of cars yielding to pedestrians at crosswalks.

Again what is this "frequency" of "severe" crashes? Are there statistics proving that this is on the rise? Almost all new cars have collision detection now and it's getting to the point you almost have to go out of your way to hit any object in view of the front camera of a car. I want to know what's driving this as it seems personal like the fluoride thing as this doesn't jive with the fact that automobiles are becoming closer to autonomous all the time which should theoretically reduce crashes all on it's own.
