Using an acronym followed immediately by terms included in that acronym

Why do people insist on saying "ATM Machine" - this is clearly an acrodundancy!

acredundanym 

A redundant acronym (ac-re-DUND-uh-nim). Typically an acronym followed by one or more words that are already represented by one or more letters in the acronym.

I created this word sometime in the mid-1990's.

Here are a few acredundanyms:

ATM Machine (Automatic Teller Machine Machine)
PIN Number (Personal Identification Number Number)
My favorite:
ABS Brake System (Antilock Brake System Brake System)
