looks like a hole I had in my honda accord back in 95. Road came to a T and dropped down a hill on the other side, lots of trees. I didn't get to stop and went off at about 35MPH, hit a tree on the front drivers side and went down the hill spinning sideways. There was a hole in the roof of the car that looked like that. Didn't go through all the way, but it did go through the outer paneling. Probably a tree.
