I finally managed to get a car running. I Drove through Severograd and the car went flying through the air. Once i got out of the city i headed towards the NorthWest Airfield. I Noticed i was unable to exit the vehicle. I tried to log off the server (official SG 2412) but it would not let me do so. So i decided i would keep driving around NWAF because i never used a vehicle before. Suddenly my xbox froze and i had to restart my console. I tried to log back on the server (SG 2412), but it kept telling me connection failed due to unknown network error. I finally managed to log back in and when i did i was in Severograd, where my car initially went flying through the air. Hope this can help you guys fix the stability of vehicles in the game.
