Well, it can be about perspective.
Good endurance riders can do laps on the edge all day long.
A qualifying session can involve pushing over the edge a little bit.
Now, I've worked with riders that were able to nearly crash more often each lap than the rest of us mortal people because their set of reaction time ability was just better than most people. To them, that was normal. It wasn't a crash in their book. But the bike attitude and all was in crash mode. Again, they were just saving it as normal practice all the time.
