I do that calculation in the article. >We can also use 24.2 mpg as the average fuel economy for a gas powered vehicle in the U.S. [10] to expand on our approach, slightly. Using this value we find a slightly largely value for total gallons of gasoline burned per year of 163 billion. That is a good point about passenger EVs vs vans and light trucks. I'm not sure if it makes the analysis "deeply flawed" as it would proceed the same way just possibly switching the actual number used in one place.
