I'm usually very suspicious of people who use Latin. I was simply pointing out that even its direct translation is meaningless nonsense.
Well, the direct translation is inaccurate so that probably doesn't help. Try reading up on "argument from authority" or "appeal to authority".https://en.wikipedia.org/wiki/Argument_from_authority
The point is that using an advanced driving qualification (e.g. IAM test pass) to support an argument when it is arguably not a qualification and certainly not authoritative is a bit silly. If the argument cannot stand without the fallacy then it is weak and will fall.
