Uber announces that it is changing its app to inform riders of the price of their ride when they book it, rather than simply providing a surge multiplier. The move is prompted by the observation that UberPool users, who do see the ride price upfront, are more likely to continue using the service. Price changes triggered by destination changes will be sent to riders in real time. Changes to routes due to traffic or other reasons not under the rider's control will not result in a change to the price charged upfront. The move is not an end to surge pricing but rather a change in the way the surge pricing is communicated to customers. The change, officially announced in late June, had already been rolled out at the time of announcement in several cities, and had received some commentary in May.
