People do pay attention to miles per gallon - or kilometers per liter.
The cars in most of the world have half (or less) of the horsepower
used in the United States. Automotive-savvy friends from Europe
point out that they have urban freeways with much longer onramps,
facilitated by the Great Urban Uncrowding, 1939-1945. Consequently,
they buy cars with much smaller engines than the same size/model of
car in the US.
Portland/Beaverton, with the West Hills as a barrier, might be less
amenable to small engines. I usually have to drop to a lower gear
and higher RPM to get my "underpowered" Subaru miniwagon over that
at traffic speed. But then, I usually surmount the West Hills in
a bus, and use the Suby mostly to haul stuff.
