Big thing that video shows is how the people involved make the interpretation different.
Marquez v Luthi.
Luthi is the rider behind and as we saw recently in this and other forums ........ is not the onus on the passing rider to pass with safety and ensure that they have the room etc? Is that not what some people said of argentina?
Other incidents (Marquez v Lorenzo) the complains seems to be about a passing rider failing to pass with safety?
Marquez v Espargaro - somewhat understandable due to the slight moment putting Marquez offline and he tries to reclaim position but Espargaro was there doing what racers do ...... seizing the opportunity
Last one ....... well sadly, no rider slows at a yellow flag situation be it practice or race. Don't believe me ........... check race lap times for example and you will see no appreciable drop in laptimes or sector times where a yellow has been displayed. Heck, as they say in Aussie taxi racing - yellow flag (safety car) = catch up flag.
I remember speaking with a rider once about this very aspect (he had raced internationally) and he relayed a story about slowing for a yellow at a race meet in england and subsequently was told that 'we dont slow down for those thing, we just know some .... went down'. FWIW, there was a lap record that was one broken in Australia after a race was red flagged, so flags mean nothing to these riders and I say that as someone who has near been hit by bikes whilst attending riders with races under flag conditions.
Willarott is inexcusable on a few fronts including Marquez, his team and race officials.
