We don't do descents much over 40 recently. We have gone over 50 in the past. I love the feeling of speed but often afterword, I think about the consequences of a failure. I've thought the most likely catastrophic failure would be a tire. However, a pot hole at speed could be bad - even if it didn't collapse a wheel. The only time we do fast descents lately is when I am very familiar with the road & road surface.
With some bad anecdotes, my rationalization is to figure out why that wouldn't be me. In this case it would be pretty easy to see how it could be me. That is why I think it is a cautionary tale for us all.
