This is poor analysis. The writer takes an artificially high number ($9100), divides it by an artificially low number (12,000) and then multiplies it by an artificially high number (30 mph) resulting in just about the highest number possible. Take a $15,000 car with a nice warranty and good mileage. $3 or so per hour for gas. $200/month for registration, insurance, etc. Maybe you'd get to $10 and hour in costs, but I doubt it. And the car would last for 10 years at least.
