Takes a very huge amount of time to find a cab and the ride is alloted to cab which is far away and completing a "nearby" trip. After waiting for a long time, driver asks the destination and cancels the cab, and the cycle gets repeated. Drivers should be informed about the destination as soon as the ride is alloted to them, so that they can cancel immediately if needed and save passenger's time. Hence the app cannot be relied upon during the time of emergency or urgency.
