The common theme for the discussed symbols is consideration for others.
In New Zealand we require a yellow [L] sign on cars with learner drivers (with learners drivers licenses). However I get the impression that other drivers are less considerate around a car displaying the [L] sign.
I suspect New Zealanders are generally far less considerate than Japanese. Politeness avoids a trillion sharp edges.
We also seem to be copying some of the US predilection of arsehole Ute (pickup) drivers.
