Ludwik,
I think you already gave the reason - "centrifugal force" already has a
defined meaning.  We use it to describe the outward force
experienced/observed by an observer in a rotating frame, ie; the car
driver and passengers.
The force of the car on the wall is much like the force of a book on a
table (on earth).  It is a contact force thwarted by a rigid constraint.
