 Are these batteries that they're going to make, are they going to be any better in the winter? Are they going to have any more stamina? Are they going to have any more power? And again, you have to assume that a lot of these billions of dollars are going towards R&D because, again, these are big issues that need to be solved. They're huge issues. There's no reason to put $6 billion into a factory to build batteries that nobody's going to want.
