Uber will be testing a new feature that will allow drivers to choose how much they will charge their customers. Drivers serving three airports in California will be allowed to set their fares based on Uber’s base, time and distance rates for UberX and UberXL. Riders will be paired with drivers offering the lowest rates. The new feature will be available at the Santa Barbara, Sacramento and Palm Springs airports. The move is a response to California’s AB5 law that went into effect January 1st.
