Watching the replay. Del Toro, Carapaz, and Pidcock were also involved in the accident. But they reacted quickly. They didn´t wait for their domestiques.
It's not all bad luck.
Some riders managed to overcome the moment better than others.
I think if or when the bunch crashes going into Rome next weekend, I'd like to see some guys use their ability to 'overcome' the incident and grab the GC win on the final day in that manner.
