Pro cycling is fine as it is. Yes, small improvements can be made, motly by fixing oversights like MAAAAAYBE there should have been bales or some other mitigating measure in the basque crash descent. But that was not an organizer failure. It was a '*** happens' or bad luck or part of the sport occurrence.
It sucks, but this is the sport. A beautiful sport that can easily get watered down to crap
We can say things are fine, but then there is the impact losing premere stars to such crashes has on viewership. The next races in which they were supposed to compete will lose a share of their audience, among those who only would watch because a certain rider was participating (or because a certain confrontation between riders was gonna happen). Cycling cannot afford this, the sponsors will be livid, commercial funds will decline as people turn away. Think of how devastating the situation is for Soudal and Visma right now. So I think it's significant and that the status quo isn't good enough anymore. The sport has changed and at all levels. The equipment, nutrition and training regimes yield high performances, which means everything is faster. From the junior level they are training and living like pros (which is not good). The pros, I'm sorry to say, are often racing like idiots, foolishly taking too much high risk, but this is driven by the pressure put on them to always be performing at the highest level, team leader and domestique alike. Riders have become enslaved to tech and data, at the expense of losing common sense, race instinct and craft. At the same time, the race organizations manage affairs as if the sport is the same as it was 30 years ago. I think, therefore, what should happen is that teams and organizers should work together to come up with ways to assess courses and develop a better system to signal danger spots and provide the necessary heads-ups, because evidently this generation of riders needs such advanced warning more than those in the past.
