Incentive for Fuel Efficient Cars

Gas Prices have been skyrocketing recently, and many Americans are struggling financially because of it. However, the op-ed writer for the New York times, Richard A. Daynard, suggests we increase gas prices even more by creating larger taxes on gas in this Op-Ed piece. He suggests that by doing this, it would encourage more Americans to turn to fuel efficient cars that benefit the environment. 

While, it is important to help the environment, and fuel efficent cars are a great alternative, I think that by raising gas prices even more, we would be harming many Americans. Many people may no longer be able to afford gas if the prices are so high, but they might also not be able to afford a new, more fuel efficient car. Because of this, they could have consequences of not being able to transport themselves to their job if they cannot afford gas.

I think there has to be some other incentive to buy fuel efficient cars other than rising gasoline prices. While I fully support cutting on gasoline usage, harming many Americans, and their ability to transport themselves to work is not the best option.

Are there any other ways to create incentive for fuel efficient cars?
