I think the citations quoted above from multiple sources generously support this. Again, that is not at all saying that all of Europe was rebuilt in the 1950s-1960s willingly and entirely to be car centric. But, the _planning_ of new construction/reconstruction were similar during that period in both the USA & Europe (and Europe by-and-large stopped their new constructions in that style around the early 1970s while the USA by and large did not). There is even a mention in one of the quotes of a lot of that construction having been torn down.
I'd say Warsaw, Prague and Paris are all great examples. Warsaw was completely rebuilt and downtown is car centric (looks very much like an American city). Prague was somewhat unscathed and has a very historic layout, Paris is a mix of reconstruction and historic urban planning. The point remains that there was a pretty specific car-centric urban planning style that dominated in Europe in the late 1940's-1960s.
All that is to say - European urban planning was also, at one time somewhat recently, largely car centric. It is really notable that stopped being the case and is an example for US cities - that they can also transform away from being fully car-centric.
