Europe isn't a country though - difficult to do a comparison as a about 40% of Europe is the European part of Russia which has a much lower road density than the US, mind you European Russia is going to be the part that has the highest road density of that country.

And almost 20% of the US is a former part of eastern Russia with really low density. :)

I wonder if it would make sense to base the comparison on road network density in areas that are above some threshold for population density?

i.e. Try and measure how many roads there are in areas where most people actually live?

Only if you're trying to intentionally cherry pick the data. Population density inherently affects road networks, and that will be reflected in the data.
