Crashing your car is an error. Crashing your car while lecturing someone else about safe driving is irony.

In this case it seemed like you were making a point about the strict legal sense of a word, but misusing a different legal term to do so.

You're describing hypocrisy.

Irony is the opposite of what you’d expect, or incongruity between what is expected and what occurs. I expect someone lecturing on safe driving to…well, know how to drive safely.

Hypocrisy requires deception, not ignorance.
