I don't think you need to act any further on it. You told her that you did not care and that it would have no relevance on you transporting the kid. My guess is that they are trying to avoid a situation where cars pull up, kids gather around, and a parent refuses to take a kid and makes a scene.
I guess you could have said, "Thanks for letting me know - I generally frown upon anyone having sex in my vehicle, so I wouldn't anticipate any problems."
