Secondly, yes, lower pressures can be faster on the road.

Road and track have very different demands. On the track, low pressures can severely compromise handling on banking, maneuvering at the speeds we see.

And, we don't have "rough pavement" conditions (well - some tracks do, but that's beside the point). His analysis is based on the fact that lower pressure allows the tire to keep the system moving forward, rather than converting forward momentum to upward momentum (bouncing) when encountering obstacles. That's very important information for roads. That is not useful information on a track.
