Uber has launched what they call, Route-Based Pricing whereby customers are expected to pay more for going to places that are popular. They have recently launched the service to a select number of states in the United States.
For example (Local example): Hiring an Uber from town to go to JKIA will cost more than hiring one from town to go to let's say, Kawangware.
Also, besides popular destinations, routes that are used by most customers are going to attract this pricing too. For example, using Thika RD, is going to cost more than using Juja RD.
Unfortunately, the extra charges for popular routes will not translate to more profits to the drivers. Instead, all the monies will go to Uber's pockets.
Personally, I use Little. The live pricing makes it convenient for me to know when to end my trip and pick a matatu if I'm yet to reach my destination. That has never happened though. Hehe!
