I agree with you comments. The added drag on the engine to run the pump
causes more work to be done to drag your car around. If it takes more
work to drag your car around, then you must burn more gas, if you have
to burn more gas to get the same job done, then you will be polluting
more and wasting more fuel....
Were the air pumps a good idea?
