There’s a trend towards lower speed limits in cities all over the world, but why is this happening? What is the research behind it? And what is the “correct” speed limit for cities, anyway?

Spoiler it is 30km/h. After that noise and injury risk/severity shoot up. It is the compromise speed.
30km/h is about 18 mph. That’s gonna be a hard sell in America.
This would be restricted to city streets. If you want more speed, use the highways or bypass roads that (ideally) aren’t anywhere near residential or city areas.
And the additional speed actually slows things down on congested roads, because you need more traffic lights (among other reasons).
