Just go to NoSenseYet.com, find where it says something like "DTR Daytona AI Fix," download it, and unzip to your DTR Daytona or Daytona Speedway 2k12 folder, go to the track.str, erase the game = 1 part, maybe adjust the pure/prod/race difficulty, and you're good to go! I tried it!! Let's go Superspeedway racin'!
