The cost of your trip may change if you add stops or update the destination, or if the route changes dramatically in the event of traffic jams or some roads close. In the event that this occurs, the fare is calculated according to the actual time and distance traveled for the trip.
We are always keen to work to improve the process of calculating the cost of a trip, and some factors may sometimes affect the accuracy of the cost estimate of the trip due to limitations in data or technologies such as accuracy of maps, internet connection, traffic and the quality of positioning techniques.
