You're crazy. Descending is far more dangerous, for a variety of reasons.
Maybe descending is more dangerous than sprinting in the same vein that flying an airplane is more dangerous than driving a car. The assumption is that the outcome is more catastrophic when there is failure. But do you think there are more failures per rider minute of desending than sprinting? I don't have the stats at hand. Seems like sprinting has a much higher probability of failure (rubber side up vs down). Now once you end up with rubber side up, I can see descending having a more lethal outcome, but that's only you crash. But what's the odd of crashing per minute descended. It seems dramatically lower than the 10 seconds sprinted in 10 stages per grand tour x 200 riders. If you add all the rider minutes of descending in a grand tour, crashes are really rare on a "rider minute" basis. But when they happen they look really bad like airplane crashes.
Crashes while descending don't just "look really bad." They are really bad
There is more kinetic energy, which increases with the square of speed. Sprints can approach 45MPH for a couple of seconds. Descents can top 60MPH for long stretches.
There are turns. (bike race sprints have a finishing straight).
There are things like trees and cliffs. In sprints there's generally just tarmac and other riders.
It's just more dangerous. No one here is confusing "more likely" and "more dangerous."
I believe to quantify danger, probability/likelihood factor into more safety equations?
I think we are on semantics. I think we can agree that the outcome of descending crashes is more dramatic/catastrophic.
But so is flying in an airplane versus driving a car. But driving a car is generally viewed at least by safety experts as being more dangerous than flying. Dangerous "seems" to incorporate all the probability and stats as far as understand...danger seems to be quantified as fatalities or injuries per driver mile. If we want to define danger as "how bad does it get", then OK no question, flying and descending would generally be worse than driving and sprinting respectively (like you said, the former there is more kinetic energy to dissipate and what you are bailing out is likely more extreme (no runway, no built up finishing chute). I still feel that descending is less dangerous than sprinting mainly because of incidences per rider minute is very low, not because of outcomes. Do the math and for all the rider descending minutes, there are very few crashes. it just "sounds" unsafe. I don't think the math would show it as being dangerous relative to sprinting.
We'd need to go to the Giro or Tour organizers and do a roll up. Probably you would have to use "crashes" in general keeping out degree of injury. To my best knowledge the only death in the TdF in 30 something years was Fabio Casertelli on the Col d'Aspin descent in 1994. I can't recall any sprinting deaths, so on that card, descending would appear to be more dangerous. But if we just roll up all crashes in each discipline, what would we see?
