GDP/Mile in various countries in 2008 - see text for details of methods
I can't find any international data that fully harmonizes with US VMT data. However, at Eurostat, I did find data on passenger miles in cars in various European countries. In the US, VMT will not be very different from car passenger miles (there are about 10% multi-occupancy cars, but offsetting that about 8% of vehicles on the road are not cars). So I used the IMF PPP GDP data, as well as the European mile data, and US VMT data from the FHWA to compute the above comparison. As you can see, the US is toward the bottom of the European countries, but not off the scale. The relative oil efficiency of most of Europe appears to come from fuel efficiency of the average vehicle more than being less car dependent.
