John Williamson gurgled happily, sounding
much like they were saying:

France, Germany, Holland and Belgium, to name just a few, have plates
that relate to the owner, not the car

Belgium does.
France most certainly does not.
I'm fairly certain Germany and Holland don't, but wouldn't swear to it.

Germany does, with the plates being removed when the vehicle is sold,

Yes, but they can't legally be swapped between vehicles in the same way
as Belgian ones are.

The French plate, last time I checked, relates to where the owner lives,
and does not follow the vehicle. If the owner moves home to a different
Département, then new plates are necessary within a short period of
moving.

Indeed. But if the car stays within the same dept, the same plate stays
on it. Anyway, they've changed that completely as of this January, and
have moved to a single national registration scheme with cars wearing the
same plate "for life".
