We were rounding a 90% turn on a small country road and they were waiting as we came out of the sharp turn

Driving late at night down a 2 lane country road. As we rounded a 90% turn they were their waiting and they were very still until we were right beside them and at that moment they broke off and started hovering over top of our car. As they were doing this one of them was like going in crazy directions moving in ways nothing of this earth can do and they were completely silent. They would not leave us alone and stayed not even 25ft maybe above our vehicle and just kept following and staying above us except the one who was flipping, floating, and moving crazy like. They followed as we drove very slowly and at one point we stopped and so did they hovering over us in silence. They did this for about 45 minutes until we made it to the Ohio river and at that point they flew off so fast they just disappeared.
