Are there any jurisdictions where driver's licenses or car registrations are not required?

In the US, Canada, and Europe, motor vehicles are fairly heavily regulated, and in order to operate one on a public road, the vehicle itself must be licensed/registered (evidenced by a “license plate” or “number plate”), and the driver must have a driver’s license.

Are there any jurisdictions anywhere in the world where this is not the case? E.g. is there anywhere in the world that one can travel to and drive 100% legally on public roads without a driver’s license from a recognized jurisdiction, and/or drive a car that is not registered with the Government, or with a government where there is cross-acceptance?

Somalia hasn’t issued driver’s licenses (or any form of ID whatsoever) since 1991, and I have a feeling license plates aren’t exactly required either.

Queen Elizabeth II can drive on any road she wants to in her realms with neither a driver’s licence (she has one; it’s just expired) or licence plates. IIRC her viceroys don’t need licence plates on their official cars either.

I’m going to guess that is so in Antarctica, but whether that counts as a jurisdiction I’m not sure.

How about the Vatican? Although maybe there aren’t any public roads there.

Edit: actually, the island of Sark would qualify. Cars are banned, but that leaves agricultural vehicles.

If the Vatican maintains and regulates its own tiny postal, telephone, and rail systems, I’m pretty sure it does the same for its roads, which probably includes issuing driving licences and laws regarding the same (or else it has some agreement with Italy to handle this on its behalf).

Cameroon has no system of vehicle registration.

Vatican licence plates in the wild.

Interesting about Cameroon. Didn’t even sven live there for while? How does that work then? My experience of African nations is that they just love bureaucracy, especially when trying to cross borders with vehicles where there might be some taxes, bribes or beer money involved…

Then how do they have license plates?

Whoops, guess I should have double-checked before posting. I don’t know where Wiki got that, it appears several other sites are repeating this falsehood.
