"The AI vehicles were extremely aware of any passing tactics that we tried to pull off, swerving and fiercely cutting off advances that we or other cars tried to make."

Goos sign, to call previous GT ai blind idiots would be an understatment.

agreed

Well I guess that makes it one down one to go. Now if they can only get car damage in the haters can move onto realtime weather effects, and croweds that take a piss and shit at Daytona.

I could be wrong but I thought car damage was confirmed.

edit:

Gran Turismo 5 Prologue To Feature Car Damage, Improved AI, Better Physics

I don't think the article explicitly states that its confirmed but I haven't read it yet, just searched on google right quick.

edit2: It does say there is a car damage system planned for the game but doesn't mention how in-depth or good it will be. So its a step in the right direction but not confirmation of a thorough system quite yet. To me it seems likely it will be good, since there is no reason to do a half-assed job on it when the fans clearly have made a point to request this feature.

If there is damage there will be an option to turn it off right?

I have always hated damage in racing games, they never get it right.

No clue, the article was pretty vague

As far as damage every part of the car is made like in real life. They did that for one reason, damage.

I think they should ask EA for the damage engine in Burnout because that engine is sick. Of course mabye Poly has something even better, in that case I will probably have to shit myself. All I care about is that this is going to be the sim racer to end all sim racers, and that is just awsome.

EAs damage is way to fake for Pd, they are going for realism like always. Car nuts first gamers second, that is what sets GT apart from every other racer.

They promised better AI with GT3 and 4. In fact, I remember claims that drivers would have "emotion" in 3, and that if you passed a certain car, he would later try and screw you over.
