OK, some do in this table, but I'm not sure how accurate it is.
It lists my country as one of those countries, and we definitely don't use space as thousands separator (we use period).
Perhaps what the table shows is just that this is the "SI style", and assumes that countries whose scientists and units follow the SI also follow this way of thousands separators, but we don't. We just use the SI units -- and even our scientists use period for the separator.
