 Yeah, it's been pretty fun. I think David most recently has had a lot of experience driving a lot of test vehicles for some of the OEMs. So he's very much trained in the moment right now to really dissect what a vehicle's doing and how it's behaving. And it's also an advantage for us that he's not under the weekly grind of having to get to the racetrack every week for us. So it's been a really good culmination.
