The model seems to be on the lines of Uber, but without its customer service ethos. They basically line up drivers (private motorists and taxi firms) to supply services to travellers. I'm not sure how validation of drivers' credentials and insurance work; and many of the complaints suggest the company washes its hands after matching motorist with passenger.
