Yeah but your examples are members of the same community. What is weird and endearing is that people who have never been on a boat will wave at people just because they are on a boat. Conversely, people on a boat will eave at people on land. Its as if a transport vehicle was a ride. A jet ski or something.
As an aircraft crew member, I can confirm: it is all vehicle types, it can be initiated by the vehicle or the ground person, and we all love it. Not really sure about the community size, it’s not like I’ve ever known anyone I waved at.
The same thing happens if you ride motorbikes and see another rider, or drive an old combi and see another combi.
Also happens in all cars in some of the rural areas in my country.
My only theory is once a community is small enough, the hello wave is used.
Cars (pickups) one or two fingers from the steering wheel.
Bikes (bicycles) do this if they aren’t training
