Study: Ride-sharing apps use AI to charge varied prices for same trip

Ride-sharing services like Uber and Lyft, often perceived as offering transparent pricing, are in fact employing artificial intelligence to present different fares to customers for the exact same journey. A new investigation by Consumer Reports, an organization founded by the U.S. Consumers Union, has exposed this dynamic pricing strategy.

Uber and Lyft routinely charge different customers significantly different prices.

The study found that price variations can be substantial. In one instance, a single route in Kansas City, Missouri, generated 29 different prices for 55 potential riders requesting trips at the same time. In another test in Phoenix, Arizona, after accounting for discounts, Uber fares for a specific trip ranged from $41.21 to $56.96, a difference of about 38%. Researchers controlled for time and location variables, yet significant price fluctuations persisted.

In a market as open and dynamic as ours, with nearly 1.7 million trips and deliveries happening every hour, the definition of a trip is not just about when it's requested but also what's happening around it, not just the destination.

While Uber and Lyft maintain that their pricing algorithms consider multiple factors, including demand and time, they have questioned the methodology of the Consumer Reports study. Uber stated that prices change constantly and are influenced by surrounding activity, making direct comparisons difficult. Consumer Reports, however, observed that approximately 11% of the 'discounts' offered by these platforms appeared to be based on originally inflated prices, suggesting a potentially misleading practice.

In our investigation, we found that about 11% of the discounts were from what appeared to be inflated original prices.
