Game Theory Explains Why Only 2% of Flat-Stage Tour Breakaways Win

Summary
Only 2% of breakaways on flat Tour de France stages stay away to win, a pattern the analysis says is better explained by game theory than by physiology or physics alone.
Sponsors push teams to seek TV exposure, giving riders an incentive to join breakaways even when the peloton usually has the collective power to reel them back.
At 25 mph, air resistance makes drafting crucial: the peloton shares the workload, while escapees spend far more time in the wind and major yellow-jersey threats are rarely allowed clear.
Mountain stages change the calculation because drag matters less, lifting breakaway success rates into the 40s, but late-race self-interest can still fracture cooperation and doom the move.
