If the pack accelerates out of a corner faster than me due to reduced inertia i will be off the back and can do the rest of the race on my own. That's something i have some experience with, unfortunately. If its a sprint i will lose the sprint. This is all normal mechanics. The only situation it doesn't do anything is in a flat time trial which starts with everyone already at the speed they will hold for the race, which doesn't have any change in road or wind conditions nor any corners. I doubt a race like that exists. maybe the triatlon comes closest because of the very long distances involved.
