It's amazing to me as an American how little need Europeans have for large American-style vehicles. I see Audi station wagons in Switzerland pulling horse trailers (with horses in them), doing 100mph on the freeway. In the US, anyone who pulls a horse trailer once a year would have a dualie diesel HD3500 with exhaust stacks, as their daily driver.
I've noticed reverse anecdotal evidence when I saw cars with ridiculous 6.5l engines in the US and Canada. It's amazing to me with my western European background how energy inefficient the US and Canada are per USD of GDP.[0][1]
It must be so much harder as an individual to make energy saving choices in an environment where those are an afterthought.
