So what happened was we were playing on the server DayZ US - SL 2500 (Persistence ON) when this happened. The version we were playing was version 1.02.151522 on PS4. My friend who was driving an Ada 4x4 was trying to drive through a small patch of forest when the car glitched out and flung him in the air when he drove over a tree that had naturally fallen down.
We managed to get footage of the incident happening. https://youtu.be/6J_m_fbrjyE If you want to see where exactly the incident happened then skip to 1:47 in the video. I must warn you that the audio might be a bit loud since he was pretty surprised of this happening.
