From the article:
See the U.S. flatlining in transit miles per capita
A devil’s advocate would rightfully argue that that’s expected given the much lower average population density of the US -- the same factor that made it a struggle to get broadband Internet to everyone in the US. Bizarre to use a nationwide per capita as a basis for mass transit comparisons. It should be a city-by-city comparison that groups cities by comparable population density. US cities would likely still come out behind and embarrassed, but more accurately so.
Consider the marketing angle -- instead of saying “the US is losing” (which diffuses responsibility and makes plenty of room for finger-pointing), instead say “@conditional_soup@lemm.ee’s city lost its ass in the bi-annual city infra competency competition”. Then that mayor has some direct embarrassment to pressure action.
