Question

brainstorming fuel efficiency ideas
special shock absorbers are just one way to make cars more fuel efficient. changes to the way we use cars can also make them more fuel efficient. what are some ideas you have to make a car more fuel efficient? some ideas may change the design of the car, and some may change the ways current cars are used.

Explanation:

For changes to car design, aerodynamic shapes can reduce air - resistance and thus fuel consumption. For changes to car - usage, carpooling can increase the number of passengers per trip, making more efficient use of fuel.

Answer:

Changes to the Design of the Car: Use aerodynamic shapes to reduce air - resistance.
Changes to the Ways Cars Are Used: Carpool to increase passenger - to - fuel ratio.
