That number is very obviously incorrect. Fuel prices alone are currently close to $0.11 per mile for a brand new Prius getting the manufacturer's estimated MPG

That number is very obviously incorrect. Fuel prices alone are currently close to $0.11 per mile for a brand new Prius getting the manufacturer's estimated MPG (58/53). Even if you assume fuel prices at half of what they currently are and zero expenses other than the upfront cost of the car and fuel, it would take 500k miles to hit an amortized cost of $0.11 per mile.
