Never been a Sky/Ineos fan, but Bernal was, for his character and class, just too dignified not to like. The interviews he has given and the charitable actions he has made for the struggling Colombian community, convey a humble and thoughtful person who is clearly just a good bloke.
This accident should have been avoided, but it's useless to seek blame now, unless criminal negligence is at stake - for example, was the bus parked in a legal spot? Traffic and driving customs in South America are often quite chaotic, for which cycling there can be laden with peril. On the other hand, even such maniacle planning as Ineos is known for was not enough to prevent this terrible accident from happening.
Hopefully Bernal's injuries won't have dramatic consequences for the rest of his career. Fuerza Egan!
