On Monday, Mark Cavendish won a silver medal in the omnium after a controversial crash, which he caused. Many, myself included, think he did that on purpose, both based on the footage (https://streamable.com/hyo2) — in which he can bee seen looking back twice — and his "moments" in road cycling, which are well known by cycling fans. Cavendish has not been found guilty.
I was watching BBC and the commentators barely spoke about the moment and didn't ask questions about it when a reporter interviewed Cavendish after the race. In my opinion, that was quite remarkable.
