Just a heads up. I was driving a long the high way at high rate of speed when I hit like a hole in road and my car completely stopped but my speed was still high. NPC Cars ran into me and all stopped with me. After I hard quit the game and try to load it, it made a sound where it sounded like a cd was stuck on a song and wouldnt get post the start screen. After a minute it would kick me out of game. The only way to fix this was to hard restart my xbox.
