Do men know when they're mansplaining?

To comment on or explain something to a woman in a condescending, overconfident, and often inaccurate or oversimplified manner".
Funny examples from my own life:

The man who will explain to the woman where her house is, even though she lives there and he was unable to find itThe man who knows nothing about music, yet feels the urge to explain "how all songs are really the same" to a woman as soon as he learns she's a musicianThe man who insists on explaining how to move a file - to a female network engineerWe've all encountered it. I'm sure most men have heard another guy do it too.
But, why?
Are men aware of doing it?
What's the most hilarious example you've heard?
