If you assume highway cruising to be 60mph, that's only 20mpg. That seems a low average for modern cars.

- mikeash 9y agoThe average MPG of a new car is only about 25, and the average age of cars actually on the road is over a decade. And 60MPH is a slower highway cruising speed than I've seen anywhere outside of big cities or congested areas. 75+MPH is far more common.
