enabled

Preconditions:

• a route is provided via MapboxNavigationViewportDataSource.onRouteChanged

• updates are provided via MapboxNavigationViewportDataSource.onRouteProgressChanged

When this option is enabled and the preconditions are met, the geometry that's going to be framed for following will not match the whole remainder of the current step but a smaller subset of that geometry to make the zoom level higher.

This has an effect of zooming closer in urban locations when intersections are dense and zooming out on highways where opportunities to turn are farther apart.

Defaults to true.
