Hi everyone,
I noticed a strange AI bug that is quite easy to reproduce. Basically what happens is that the AI cars start spread out, and later on in the race, all merge together into single file. If you rewind early on in the race and resume, they immediately stop what they are doing and go into single file. Even if it is at the beginning of the race. So, their behaviour instantly changes after rewind.
Start a new race in campaign (not sure about free play) in which you are in the middle of the pack
Start driving forward once the lights turn green (obviously)
At this point, the cars will be fairly spread out over the field.
You will not be able to use rewind yet.
Just before the first corner (depending on the length of the straight), hit rewind
Resume again
Watch all of the cars magically swerve into single file
