As the commentator said, “Bike crashes can easily happen”.
I think all cyclists are aware of the risk. For less experienced cyclists, crashes might shake their confidence a little bit and make them become more careful to avoid the crash again; perhaps they might go a bit slower than the speed before.
For more experienced cyclists, they probably know that crashes are inevitable and thus won’t be affected as much. They will be more likely to just get up, get on the bike and move on as fast as they could.
