Well, except not really.

First, it's an expensive mistake, that's a legit reason to be upset. Second, it was a "dumb" mistake. I'm not coming down on OP, but finding out how anxious a driver your kid is at this point is also stressful.

And, last - this accident was a no harm one, but it could easily have been vastly worse. that kind of thing is also upsetting to a parent.

Now, if Dad holds this over them forever, he's out of line, but being upset for a day or so? not really out of line.
