RouteInstructionBase class
A single route instruction used for route guidance.
RouteInstructionBase models one maneuver (for example, a turn, exit or follow-road instruction). It exposes the instruction location, localized text, images (turn images and realistic intersection renderings), signpost details and time/distance metrics used to present guidance to users and in UI lists. Instances are obtained from RouteSegment.instructions and should not be constructed directly.
For real-time turn-by-turn updates use NavigationInstruction which is produced during navigation.
