Question
According to the US Energy Information Administration (USEIA) approximately 37% of all energy used in the US in 2021 was for transportation. Most of this was in the form of gasoline for automobiles. Using internet sources identify at least 3 things people can do to increase their car's gas mileage, that is to reduce their gasoline use while driving. Briefly explain how each of these results in increased gas mileage.
