I'm a little foggy on "per capita car" which may include vehicles like shipping company truck fleets, taxis, etc? The gallons consumed and mpg seems to be in line with that I would have guessed. (Before finding ecomodder I was probably right around those numbers in consumption and efficiency).
It's passenger car only (which may include light trucks - it's been awhile since I put that together).

And, Doh! I misread my old post (which is why it didn't say passenger vehicle mpg) disregard those mpg numbers - that's for all motor vehicles (which does include commercial vehicles).

BTS | Table 4-11: Passenger Car and Motorcycle Fuel Consumption and Travel has the passenger vehicle data - it looks like the graph will have a similar trend, but offset higher leveling off around 22mpg.
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
