The 2024 Darlington race report is a great example of how numbers never tell the entire story of a race. We’ve got side-by-side racing but not a lot of official lead changes, and bold moves, some of which worked and some of which didn’t. […]
Photo-finish technology has spawned a handful of articles on how NASCAR determined the winner in a 0.001 second margin of victory at Kansas. I thought I understood the technology, but it turns out I hadn’t quite entirely gotten it. […]

The Bristol 2024 race set lead change record for short tracks, but only because of abnormal tire wear. Let’s investigate why. […]
