The driver didn’t follow the route given by the GPS
Our drivers follow the optimal route indicated by the GPS (Waze or Google Maps etc). However, the route can change depending on traffic and occasionally they might be able to take a better way than the one indicated.
Remember, since Cabify prices are fixed on the optimal route, any deviations will not affect the price of your trip.
For more information on what to do if you believe that your driver did not act appropriately, see "What can I do if I was unhappy with the driver?".
