I'm not sure who you've been talking to in the department. I'm certainly happy to learn the names, but obviously there is a need for consultation when we're looking at how we enhance the efficiency and/or the technology used in a range of sectors. That's true of light-duty vehicle standards and it's true of heavy-duty vehicle standards. That relates to short-term issues around enhancing energy efficiency. It also relates, as I said, to long-term technologies like hydrogen and fuel cells that may be a replacement for the internal combustion engine or the diesel engines that are typically used.
I know my officials have already been having some of those conversations, but if there are specific folks who have not been reached out to who you think should be reached out to, I'm happy to do that.
