> Along these lines, I find that not many people correctly calculate the cost-per-use of their car. They only think of the cost of gasoline burned, and maybe tolls and parking. They don't think about the cost of insurance divided by the number of trips, or the capital cost of the car amortized over the years of ownership. If people thought hard about the cost-per-use of driving, then other transportation options start to look more attractive.

They do think about this, which is why the second-hand market for cars is so healthy.

To be accurate, you should restrict your assertion to those people who only buy brand new cars, which is necessarily a far small population of people who buy second-hand.

There are more people who think about this (they buy second-hand) than people who don't.
