How would the compartments work? Those sections look like they can raise; who decides for that to happen? Diagonals wanting to talk when corners want to be closed off, bit awkward.

I suppose having to get in the other side is just like a taxi, would be nice for airport users especially to be able to get on pavement side with luggage. It’s cool anyway. I know it’s autonomous but does it work on a track system? Video looked a bit like that.
