The early fleet investments are relatively small. There are long-haul truck investments. We have a company that has chosen to switch to natural gas. There are also cases in which an individual municipal garbage truck has been purchased, or more than one, so we're not talking about massive amounts of information yet, but I would support your call for a more sophisticated way of collecting that information.
We're doing the same with the electric vehicle agenda for the same reasons. What is the actual range associated with given conditions, given vehicle weight, etc.? The only way you can do that is through some kind of automated system.
