Google added a new feature in Google map for auto rickshaw as a new transport mode, this feature is available for Delhi users. You can find this option under public transport and cab section of the app.
This feature is similar to the cab feature where the map shows details such as fare for the trip, the routes for a destination. Google uses traffic data to generate fare for a journey. If this feature succeeds then there may be chance to see this feature in major cities of India.
