Came here for this. Pickles are like a researcher’s??? Progeny? A researcher’s what? I must know.

Also something about Harry Potter in the first lines.

Edit. It’s grumpy! But I don’t know what!

While true, cars that breakdown don’t come to a complete stop, generally. You should put your hazards and roll to the shoulder. That’s not always possible, of course. But if a vehicle is clearly disabled, you wouldn’t stop behind it waiting for it to move out of the way, which is what happened here as well.
