superflously redundant

I hate when people use redundancies in general, but for some reason, it really stands out to be when people are redundant with acronyms. I heard someone using one of these today, which is why I thought of how much I don't like hearing it. Here are a few I can think of. Let me know if I missed any obvious ones: ATM machine (Automated Teller Machine machine) ABS system (Anti-lock Brake System system) ACT test (American College Test test) SAT test (Scholastic Assessment Test test) HIV virus (Human Immunodeficiency Virus virus) PC computer (Personal Computer computer) VIN number (Vehicle Identification Number number) Not the end of the world, but it sounds a little ignorant when people use them. Such is life.
