> That means the technology problem is now a money problem. And not even a horrible one. A bus that is driven half as much per day will wear out (about) half as fast. Which means, although you do have to buy twice as many buses up front, the number of buses you have to replace per year won't change. So in the steady state, the cost of buses isn't actually that much worse. There is still some penalty for needing more buses, though. For example, you have to pay more to store buses. Also some maintenance is more of a function of time than mileage driven. And you're tying up more capital, which may mean more bonds or opportunity costs.
