this term stems from maritime law and has carried over into aviation law at a later time, of course. Much of what we are all familiar with in the vehicle codes also stems from these early maritime laws, which state that the slower, less maneuverable "vessel" has the "Right of Way", obviously owing to the fact that the more-maneuverable vessel can negotiate more readily, regarding avoidance, than the larger, less-maneuverable one. Bearing that in mind, however, if two vessels, aircraft, vehicles, of the same class, are approaching at a 90 degree (or nearly so) angle, then, the one to the other's right enjoys the
Right of Way. When you're mixing entities (people, golf carts), of course, the correct answer is often provided by law, statute, rules or "established good operating practices" (good luck on the latter
). Good practice, IMHO, in spite of this, is realizing you could be "dead right" if intransigent while operating in the real world.
