How about we focus on trying to fix the issue that everyone is complaining about instead of trying to add a bunch more options that may or may not be even possible?
Right click run as admin on trainer. Run game and get to the point where you are getting into your car. Alt tab out to the trainer and press F1 to activate. Alt tab back to game and use options as instructed. If it's still crashing then something is interfering with the trainer or your game version is different.
