The word vehicle is up to interpretation, so it helps to not use umbrella terms like vehicle. Anything used to move goods or person is technically a vehicle. However in the a conventional understanding it is the embodiment of what would move goods or person, functional or not, to carry out a task not recreational unless also used with the intent not recreational. If both it becomes a recreational vehicle.

Recreation / Not Practical = Other

Not Recreational / Practical = Vehicle

Recreational / Practical = Recreational Vehicle

You don't have to agree with me on this. I know the definition says otherwise, I'm just speaking on the perception of what people think in society a vehicle is. As it would sound really funny to refer to toys as vehicles.

Also to expand on this. Drones they are recreational but also practical, you might use your drone for recreational things but nothing practical so it is just a drone. But the second you start flying packages it becomes practical. This makes it a recreational vehicle. If it is exclusively for delivery like Amazon Drone, it is just a vehicle.
