What numbers? It just asserts that society pays $9.20 for every $1 you spent driving. I don't see how that alone is plausible. A quick google says the annual TCO for a car (ie. how much "driving costs you") is $9,561[1]. If that figure is correct, then each car is costing society a whopping $87,961/year. Keep in mind, the US GDP per capita is only around $60-70k/year. Yes I know each person doesn't necessarily own a car, but it seems implausible that cars are actually costing a significant fraction of the GDP.
