Riders assume that a ride‑hailing app will always give a fair price, so they press the button without checking the final amount. When the app hides the surge multiplier until after the driver is assigned, the rider’s decision point is already passed; the cost becomes a post‑fact detail rather than a barrier.

This design shifts the friction from price comparison to acceptance, letting the platform extract extra revenue while the rider feels the inconvenience was minimal. Uber discovered that removing the upfront fare estimate reduced booking abandonment during peak demand, because users who might have balked at a visible 3‑times multiplier instead completed the ride and paid the higher fare.

The extra income then funded driver incentives and faster match times, which in turn attracted more riders and drivers—a self‑reinforcing loop that deepens the network effect. The trade‑off is subtle: a smoother checkout experience masks price volatility, but it also makes the platform’s pricing power less visible to competitors, reinforcing its competitive moat.
