Public order offence for swearing during close pass

So here's an odd one. Just posting it here for any advice, though as a CyclingUK member, I'll also contact them to hear their view.

I was close passed in a really bad way a while back - basically, nearly squeezed between a barrier and a badly driven car. During the process, I "dropped the f-bomb" four times. I submitted the footage to the police, including an apologetic note for my language in the footage. The police are taking it further with the driver, apparently, but the driver has now complained that I was using foul and abusive language, and thus a public order offence. I'm now going to be interviewed under caution for a public order offence!

I've sent some footage to the police before which has included some fruity language, but never had anything like this before. Frankly, the whole thing is embarrasing that this has been taken this far. Surely there is no public interest in pursuing someone who lets their language standards dropped when narrowly escaping a serious road incident?

Any thoughts or advice welcome.
