David Ragan changed lanes on, crucially, not the final restart. He was already banhammered to the tail end of the lead lap for
the last and kinda iconic green-white-checkered restart.
...and then his career went right down the toilet.

They got the Ragan call right while the race was still raging, but they can't figure it out now after the dust has settled? It's also not 1959, where NASCAR can look at photos for three days before determining whether Lee Petty won the race or not. Instant replay is a thing that exists in 2024.
Unfortunately, NASCAR has a history of making the rules up as they go along, inconsistent penalty application, and the occasional favoritism. Not that sports with just as many cameras, a host of stewards, infinite camera angles, 45 minutes of time to adjudge an in-race penalty, and a rulebook thick to the point of obtuse is these days able to
penalize a clear-as-day jump start as a jump start due to technicalities. And I'm on *Team Lando*...!
