Sat Nev routing - does not make sense

I have so far avoided acquiring a Sat Nav device simply relying on knowledge and a dog eared ancient UK atlas.

Then I purchased a Tablet-- and to play around to learn its foibles

It collects Sat Nav data from the mobile source/

So I set to to plan a journey from my town to one that I know very well and its many routes of access.

The result led me all around the country side and motor way- when in fact there are several shorter less intricate routes.

I wonder how the 'logic' or route finding works.

It is little wonder truckers get stuck up alleys
