Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The article "Driverless cars are coming" states, "The cars [Google cofounder Sergey Brin] foresees would use half the fuel of today's taxis and offer far more flexibility than a bus."

Obviously, driverless cars would increase the efficiency of vehicles and use half as much fuel.

This would benefit both the owner of the car and the environment.

Pollution from cars is a real problem and, if cars only used half of the fuel, then this terrible pollution would be minimized.

Also, if the cars use half as much fuel, then our natural resources would be preserved and the cost of driving a car would be lessened.
