Let's pretend the car didn't hit he pole, didn't come off the ground and did strike the priest's car. How many ways, by changing various parts of what happened, could that have been avoided?
It could hit the pole in just the right way, as actually. happened. Thousands of things could have happened that caused the priest's car to be somewhere else at the time when the black car entered the road. At the speed the priest was traveling, how many seconds travel would it take to avoid the black car? Two? We could work it out, but a very short time I'm sure. OK, so maybe the priest cleaned his teeth for two seconds less time, and left his house two seconds earlier, just enough to be past the point of impact. Maybe he couldn't find his car keys for a minute or so. He arrives at the accident site well after it happened. A thousand and one variations on his route could make him vary his speed and avoid the collision. Most of these "changes", even if anyone was aware of them, would not be connected to the accident in people's minds.
Yet only one, the one that actually happened, would have, and in real life did, trigger the "miracle" claim. Though if we are looking for divine intervention, any of these things could have been caused by God and therefore qualify as a miracle. It's all a matter of perception.
