Sedans and gas

In 2018 17.2 million vehicles were sold and 80% were small trucks and SUV's. Both Ford and GM see the writing on the wall and are discontinuing many car models. On average small trucks get 17 MPG, SUV's get 23 MPG and sedans get 35 MPG. The average driver drives 14,000 miles per year. If everyone drove sedans that would save 250 gallon of gas per year per vehicle or 4.3 billion gallons of gas. Americans are not willing to make this change and this says a lot about the concern for climate change.
