Or do you mean where FSD drives you around i.e. Downtown San Francisco following multiple waypoints with a narrated audio track?
There's a cool app I used in Hawaii called Shaka Guides where it used phone GPS to trigger audio tour waypoints and narrated drives around the islands.
Something like that would be cool to be built into the infotainment but might be a long ways off. FSD has to get off the ground first .
