The trips that we have made to Europe, we have found the roads and streets, especially in smaller town, are not made with large vehicles. Cars, to the US drivers, are an extension of themselves. Many go into significant debt to keep up appearances. Europeans have been used to high fuel prices and they drive appropriate automobiles. Manual transmission is the standard, automatics are the rarity. TBF, the distances traveled are shorter for daily drivers in Europe, US drivers spend a large amount of time on the road, getting to and from work.
I remember one trip where we rented a car and toured a good portion of the Danish/Northern German area. The vehicle was a manual transmission and there was a feature that caused me concern until I had gotten used to it. When pulled up to traffic light and stopping and depressing the clutch causes the engine to stop. I thought for sure we would need a tow back to the rental counter. It seems this is a feature to save fuel ans when you release the clutch, the engine springs back to life. Not sure what this does to starter life.
Europeans see automobiles as a tool to do a job, Americans see a status symbol as well as transportation, imo.
