Moto's fault but BMC and second sunweb rider are to blame for it being so bad, the first sunweb rider in the train does well to avoid it, the second rider is more over on the left, has a clear view of the moto with more time to react, yet still hits it hard! His initial reaction is fast enough to have moved further over, he seems to move over and then check his movement when it's still clear on his right (could've moved further over).
Still seems an utterly stupid place for that moto to stop... They're normally struggling to get ahead of the peloton on the flat/fast parts, not sat at the side obstructing clear parts of the road, that could be what caught so many out, they didn't realise he was stopped. Also there was more than enough room at the side for the moto to be on the grass, not the tarmac.
Racing 'incident' but with something like that caused by a race moto (responsibility of race organisers) there should be some ruling that the race results for those rides involved are 'neutralised' in some way?
Or you could say some call goes up to the front to neutralise and they're paced by the commisars car or even neutralise the whole stages results, providing the riders at the front know as soon as it happens? But then you have to decide what kind of incidents are neutralised or not, as well as the circumstances as you'd get teams crashing at any opportunity when things are not going their way...
Have to agree on the other point though, much of the sportsmanship recently seems to have gone out of pro cycling.
Edit: Read somewhere that Pinot's ride on Strava still has the power data, might be worth hunting down.
