I don't think that's true, the car as mere tool is romantic anachronism. Back then, cars were central identitarian elements to the post-war, western promise of salvation. Whole cities were torn down and rebuild to fit the car. The car had ideological significance. I think, identitarian attachment to the car is actually less today, but due to the historic importance and focus, cars have become unconditional necessities in many places.

I think the reason, you frequently see "old cars as tools" in southern Europe still, is the fact most regions there only started industrialization after 1970 and were/are still greatly underdeveloped/relatively poor, compared to eg. early industrialized nations like Germany, which are super car-centric. They suffered less car adaptation at the time and as a consequence e.g. SUVs would be rather impractical in some places with extremely narrow streets. Additionally, (remaining) farmers in e.g. Germany are almost exclusively rather rich entrepreneurs managing industrialized food production on flat, boring lands, than "poor peasants" caring for traditional farms in remote villages living off tourism somewhere pretty.

Probably less due to zeitgeist/mentality, but rather geography, historic economic abilities and availability.

Can you give an example of a European city that was "torn down and rebuilt to fit the car?"

In my experience, even cities that suffered a lot of war time damage (Hamburg, Dresden) were rebuilt with every street in exactly the same place with the same narrow width.
