Those cities you mentioned already have European style urban infrastructure. In my opinion the big difference is that the drivers in the European cities seemed crazier than their US counterparts.
That’s interesting. I’m a born and raised American, but I lived in two different European countries (Oslo and Geneva) between 2014 and 2017. During that time I traveled all over Western Europe and the near east for fun and business, and besides 2020-21 I have vacationed in Europe once or twice per year when not living there. Old Soviet Europe drives pretty crazy, but other than that I have not encountered anywhere else in Europe with drivers as crazy as the US.
They have very different norms in Europe that Americans might confuse as crazy but are actually better habits IMO. E.g drivers in Florence and Rome followed few rules and basically drive by the “if it fits, it fits” manta. But they were always keenly aware of pedestrians and other drivers. They drive very light cars in streets where they can’t get above 15 mph. Even if they do get into more fender-benders, I’m not very concerned about a fiat hitting my car at 15mph. In short, their way of driving is safer and I feel much more comfortable around it.
Americans on the other hand seem to prefer deadly speeds in giant vehicles even in neighborhoods. My current neighborhood regularly sees F150s and King Ranches going 55+mph, on neighborhood streets. I saw a driver last year hit a dog they should have clearly seen and avoided because they were going about 45 mph and on their phone, they didn’t even slow down after they hit the dog. Americans regularly pretend pedestrians and obstacles don’t exist at all, and have way worse reaction times than what I saw living in Europe. Combined with the high speeds and heavy cars, driving is comfortable for the driver and terrifying for everyone else on and around the roads.
I also wouldn’t compare these American cities infrastructure to most European cities of the late 2010s. Excepting possibly NYC, which is sort of its own league in the US. Maybe they are comparable to the European cities of the 90s, but things have moved on a lot since then.

I hope you're joking. it's very rare to see a highway wider than 6 lanes in Europe, especially that runs through cities, whilst the aforementioned cities have a abundance of such monstrosities.
