So its the most famous street in London where normal traffic isnt
allowed

Is it? I should have thought that Downing Street was pretty famous ...
but try driving (or even walking) along Downing Street and see what
happens.

but it doesnt seem to be enforced at all leading to quite a
lot of supposedly banned traffic using it.

I have not noticed much banned traffic in Oxford Street in recent years.

Or does it mean that traffic is banned except for unloading, local
access, disabled traffic, minicabs etc. so infact its much like a
normal road?

Some parts of Oxford Street have a 24-hour, 7-day a week restriction on
loading. Regulations vary in different parts of the street, but there is
seldom opportunity for private cars to do anything other than a direct
cross.
