By comparison, in the auto industry, if you want to come up with a new vehicle platform, that's actually a five- to eight-year process. It involves a lot of different engineering. It involves a lot of different questions about supply chain. I would suggest that the supply chain is a little more vertical and less horizontal for the rail industry. But having said that, there is development and lead-up time. Even in setting a new standard there has to be some consideration about what that looks like.
Bottom line, Mr. Hematian, it's not a simple snap your fingers and we have a new standard, right? There are a lot of moving parts to this that have to come into play.
