The sport is inherently dangerous, which, along with the gruelingness of it, makes victory at the highest level the stuff of the gods, epic, in the ancient sense of the word. For this reason, you can take as many measures as you want to make it safer and still riders will go beyond limits, because that's what is incumbant upon them to do in the very nature of cycling. We live in the age of hyper-safety concerns, whereas cycling grew up in carefree times, initially because you could go faster and cover more ground than previously imagined without technology. Today the sport risks oblivion as the next generation won't want their children out on the over-trafficed roads and as the young are increasingly made unaware of learning how to fend for themselves, let alone in the peloton. It's a sociological problem by now, mark my words.
