Europeans are, too! LOL!
Europeans are smaller in width not height. I think vehicle size follows the rental car agency definitions. On a trip from Lucca in Tuscany to Venice, I quickly developed muscle cramps in the back seat of a “standard-sized” Ford Contour. When one of the other guys switched seats with me, he didn’t find it as spacious as he first thought (he’s close to 6 ft.). His car is a Citroen so I could see how a Ford Contour might look big compared to that tiny hatchback.
