 It would be great if we could standardize, and we could all march to the same drummer and drive that cost down as fast as possible. We're all working on that anyway. It would be great if governments would say, yeah, you got to have that right now. But then you kind of pick a technology winner, and governments take a time to do that. In the meantime, I think consumer awareness, the more you bring consumer awareness up on what the benefits can be, consumers will select. We saw that happen with airbag transition in the United States. They got in actually ahead of the regulation because consumers became aware that to get a five star rating car, if you want five stars, you've got to have a certain complement of airbags.
