This is a sad video, because it shows that the AI in GT5 blows. I've played F1 2010 and I was quite impressed by how other drivers reacted to my actions on the track (of course they made stupid decions occasionaly as well, but you can't prevent that from hapening). It shows, that there's a way to make decent AI. The current AI in GT5 simply sticks to it's predefined route...
I love how people throw out wrong information as if it is fact.
(Namely: YOU)
BTW what is KI? never heard of it.
