Disable Opponents
Race Driver: GRID: Code (Disable Rivals) Free Download
Go to your Grid Folder and then the AI folder. Remove the file \\\ “ai_vehicle_config \\\”. If you start a race, the opponents stay and you can enjoy the race. Make a backup of this file before removing so you can restore the game’s original functionality.
