Also I imagine that Navteq and the like in Europe are reliant for their main
data on the official mapping organizations of each country, such as the
Ordnance survey in the UK, and the Institut Géographique National in France.
I don't know what the equivalent organization is in Portugal but it wouldn't
surprise me if it were less well organized than in the more developed
countries of Europe.

Garmin only rely on Navteq for their data

You would have to work for Navteq to know for certain, but it would be an
enormous task for a single organization to survey the whole of Europe (or the
USA for that matter) from scratch. It would be quite unnecessary too. The
Ordnance Survey for example, has all of the British Isles mapped down to a
level showing the outlines of individual buildings. This data is available in
digitized form, and regularly updated. Most of the developed countries in
Europe will have similar data available. Why would Navteq use their own
resources to repeat this themselves?

I assume they use camera cars mainly to check on road attributes such as
restricted turns, one-way systems, lane layouts, sign-posting and so on. Of
course they can also check on new road construction and alterations but to
rely completely on their own data acquisition systems when they have a wealth
of data already available would be grossly inefficient IMO.

As it would in the long term be cheaper and they would not have to
comply with the restrictions imposed by OSGB.
