Looking like being obvious is not among Rams principles.
#4: "it is self-explanatory."
OK, I think it's a misunderstanding.
Self-explanatory refers to the use of object that is designed. It needs no explanation. How to ride a bicycle is pretty self-explanatory (even if it's not trivial to learn).
The design of a bicycle however is not obvious.
