The first rocket car only failed after the passenger side front wheel fell off. If you watch the video of it, the loss of that wheel was what caused it to flip.
But what they were testing was whether hitting the bump in the road (represented by the sandbags) would cause it to take flight. And it didn't. It drove right over them and kept going at ground level, and the myth was busted at that point. So whatever happened to the car afterward was beside the point.
