Not 20 lbs of CO2 per mile. Most of the mass of gasoline is carbon. But most of the resultant CO2 mass is oxygen. So each gallon (6 lbs) of gasoline produces about 20 pounds of CO2. So in your example of a 20mpg car, each mile is a pound of CO2.

This just reinforces how ridiculously unfamiliar I am with the actual working details of internal combustion engines - quite interesting.
