 Well, we've heard a lot about tire degradation on this new surface. Is that obviously going to be a big concern in the Reds? And how much are you going to be able to affect that with these hybrid power units? Yeah, there's definitely going to be a big change when it comes with the hybrid. I mean, it's probably going to affect it, probably increase it in some ways. But overall, I mean, the whole game for the race today is just going to be tire deg, so hopefully we get there.
