onReady result json data and navigation

Hello,
Not an issue but a question.
The data provided by the input param for onReady gives data relating to legs and and steps for route by route navigation. I would like to use this as in in-app navigation for drivers going to pick up a user. I am building a ride share app and once a ride is accepted by the driver, the navigation kicks in to guide them to the user. I was reading google navigation terms and building a navigation would violate their terms I believe. What would be the use of this data then if not as part of a navigation component? Or maybe I misunderstood google's terms?
thank you in advance

Start with the onReady API documentation and the Google Navigation terms referenced in the report. Done means clarifying whether the legs and steps data may be used for the proposed driver navigation, rather than changing repository code.
