Even accounting for how car-centric US cities are, I agree with that commenter. Yeah it may be hard to get downtown from outlying neighborhoods without a car, but sidewalks have ramps and building have access. Hell, the parking lots have designated parking spaces. Not true at all in most European cities
Edit: I guess it’s worth a little more nuance than just limping all European cities in the same category. The wealthier northern cities have definitely caught up a bit (though they all still have buildings that are completely inaccessible). The real problems are the southern cities like Rome, Madrid, Athens, Lisbon etc.
