There is a photo finish we can all view. It's incredibly close but it's also clear that Van Aert is ahead at that point and therefore is the official winner. The only debate is about where the line for the photo is WRT the black painted finish line. As mentioned above, the photo finish and that line are never the same in any race, because the black line and the black bike tire don't offer enough visual contrast for the photo finish images to work. So they always move it to part of the white line.On the AGR finish it's certainly close enough for TV pics to fool the viewer. However for the womens race last wedesday no amount of technical explanation is going to explain how Vollering wasn't given the win - it wasn't even particularly close. Given that blunder just a few days earlier, it doesn't inspire much confidence that the AGR finish would have been correct either
I think there is healthy debate about whether they put it close enough to the black line to be as fair and clear as possible, and my guess is that they can do better. It does appear that by the time they got to the black line that Pidcock won, but that isn't the metric for who wins, it's the photo finish.
