text: Futhermore, not only would there be less pollution..but we would save thousands of dollars..on gas and insurance. Gas is one of the most important things for a car, it makes it function. But also we would be fine if we didnt have it, mainly because we would save hundreds of dollars a month. The average cost for a gallon of gas is $3.70. Not only gas but insurance and repair jobs. Insurance is as expensive as it is when you wreck your car, if you're lucky enough your insurance could possibly pay for it depending whos fault it was who caused the accident.
