Revealing mistake: When Ace's car flips over you can see the left wheel is elevated over the bush. If you look closely there is a wooden plank there to help the car lift itself over the bush. The other mistake in the shot is that there is no conceivable way the bush would have flipped the car. Unless there was something very solid in front of the bush, the car would have just gone right through the bush.
