Not a ban, perhaps... but if I have two users - Alice who uses the app according to normal patterns, and Bob who consistently predicts and declines when my dynamic pricing algorithm tries to push above market pricing, and has a remarkably high look-to-book ratio - I'll want Alice to have better drivers, better service, faster pickups etc., because I'll have larger lifetime margins from choose-the-app-on-vibes-Alice than from race-to-the-bottom-Bob.

If my known-good supply is limited at any given time, I have every incentive to focus it on Alice, and I'd be inclined to try out e.g. new drivers on accounts like Bob's.

Rideshare data teams are incredibly talented, capable, and motivated. One does not simply front-run a market where the biggest players have a massive data advantage, control your latency, and are effectively unregulated.

An alternative possibility is that a rideshare company sees that Alice always takes the price that's offered so Alice receives the standard price, whereas Bob is price-sensitive so he receives personalized discounts on rides until the prices reach the amount that he's willing to pay.
