So they're *grossly*
negligent with the claim that the organizers should have paid more attention to something that has been accepted as sufficient for the last decade or more, and then mentioned it in the morning riders meeting?
...if they had mentioned it in the morning meeting and he hit it, the question of negligence would have been "well why didn't you remove it since you knew it was there and was a hazard??"
This is a slippery slope. By the end of this, we'll have to let people drive tracks on Gran Tourismo with VR goggles from a climate controlled, padded room so they don't hurt themselves. How much hand holding do we need?
It's a goddamn motorcycle; it's dangerous.
