I never understood why they didn't picture the building, with the buttons and the room/apartment numbers at each floor... That would make all conventions clear. Going negative would be obvious, and just indicate which floor the elevator is at with LED's of backlighting.
They never heard of making a UI, and just slapped buttons.

I suspect that floor numbering predates lifts (elevators) by centuries.
Stairs are ancient.
I mean, zero itself is a non-obvious concept. Its invention is a matter of historical record:

... and we still use counting systems which predate the invention of zero, such as Roman numerals.
