I found the full article:

"Check out this AI comparison between Gran Turismo 5 and Forza 4. You wouldn’t believe it but Forza 3 actually seems to have better A.I. than Forza 4. Turn 10 needs some explaining to do because this video is just hilarious. If you remember earlier, Forza 3 A.I was found to be much superior than Gran Turismo 5."
The AI in GT5 Spec 2.0 is better than AI in GT5 launch... improvements.
I would like to see a comparision between GT5 Spec 2.0 and Forza 3 
.
