Dasher Incentive Trap
DoorDash launched Peak Alerts — push notifications urging offline Dashers to go online during high-demand periods. Headline metrics look great: 28% more Dashers during alerts, 62% fewer unfulfilled orders. But deeper analysis may reveal that Peak Alerts cannibalize off-peak supply instead of creating net new supply.
