Because so many are run to the change limit, and beyond it, and don't do
enough fast miles to keep the sludge levels down, slow round
town/off-tarmac driving means more circulation/use between changes.
Take a look at some of the lube advice web pages to get a feel for it.
I run 3k between changes, not 6, and flush every third change to try to
keep the turbo from coking its bearings etc, though stopping a hot turbo
after a fast run isn't good for it anyway, keeping the engine running
for a few minutes allows the turbo to cool gradually and the oils to
keep flowing not boil off and clog the bearings with coke, flushing
helps unsympatheticly driven engines survive....
