There’s been PLENTY of “rough riding”... few claims of foul have EVER been made against a winner, and NONE were previously upheld.
Still didn’t mention many incidents.
And bear in mind most of that time there was no filming. No film for stewards. I don’t know if the fighting finish even had any replay film for them to use. Post 30s I can imagine, after the photo finish came in.
