FBT and Uber style ride sharing

When an employee uses a taxi service for travel to or from work or if the employee is sick, it is generally exempt from Fringe Benefits Tax (FBT) under the FBT taxi travel exemption. The question is, what about Uber and other ride sharing services, do they also qualify for the exemption? If Uber is considered to be a taxi for GST purposes, that is, all drivers need to be registered for GST and charge GST as they are considered to be a taxi service, does the FBT exemption extend to employees using Uber for travel?
