 And the logical progression would be like, well, we have this technology that's been around since like the late 1980s. It's actually been around longer than that. But we have a hybrid technology.

You use the battery to get the momentum going, and then you use the gas to keep it going. And that vastly, like if you're thinking about when you use the most fuel, right?
