Thats just gas though, factor in the insurance, car payment and your collecting more cans. Say he drives 12,000 yr or 1000 a month and pays 300/mth for car payment and insurance which assuming the bum has good credit, got a deal on financing, and is a excellent driver. MPGs are probably going to average 20 maybe in a lancer with the stop and go for each garbage. So your looking at $500 dollars a month for gas and paying for the car, or .50 cents a mile. So if the bum is resourceful he has to find 10 cans every mile which I guess would not be hard.
