Interesting. But whatever the rules say, clearly the camera is used to determine the winner when it's close, and therefore its scanning plane does then define the finish plane, wherever it is in relation to the painted line. That seems pretty established, surely.
Why don't you believe the camera can scan at 10 000 fps? Revising arithmetic from previous page with that figure gives ability to differentiate winning margin of 2 mm at 70 km/h.
Touchpads are completely different and in swimming/athletics the length of lanes and timing rather than position is more important.

The finish line is mandated to be 4cm wide, painted black on a wider white strip, and the winner is the rider whose front wheel breaks the plane of the leading edge of the black line first. That's what the rules say about who the winner is, no mention of a camera. Unless that camera can be reliably aligned to that plane with mm accuracy making a call that fine just isn't possible. I don't believe the camera can be that accurate, or even that the line is drawn sufficiently straight.
