Uber India — using route other than shown on uber gps map

Address:

560085

My colleagues and me took an uber cab on 28th jul evening from bellandur to kathriguppe. We told the driver to take the optimum route that we suggest which the driver denied and said he will be using the route shown by map on app. As we travel every weekday at the same time in that traffic, we know the best route to reach the same destination. The reason for denial was that the app will lock if he takes a different route. We had to ultimately spend 20 mins more than the usual travel time in the traffic by taking the route suggested by the app. I don't know whether the driver was right or lying. If not don't you thing the passenger has to be given the liberty to choose his route until the destination where he gets off is same? As far as i know, i have taken the best known route whenever i have used uber cab and no driver has given this reason. Please look into this matter and resolve if issues exists. Thank you.
