Taking on the most serious topic first--the assertion that the racing in the game is scripted--the post reads:
The AI system implemented in F1 2010 is very complex, and is certainly not scripted in any way. Every AI driver is trained with a series of race behaviours such as overtaking, defending a position and slipstreaming etc. On top of these behaviours we have a unique set of characteristics. These characteristics are defined per driver so you'll notice some subtle differences. Some drivers are better at race starts or are better at overtaking (they look for narrower gaps), or are better in the rain, or are more aggressive, or are better around certain race tracks. We also have a system which can make certain drivers have a particularly good or bad race depending on a number of factors.
The post goes on to definitively state that in races every AI car physically drives the race just like the player does.
This is not the case, though, in practice and qualifying. Citing the fast-forward and jump-to-sector features as the cause, the post reveals AI times are, "calculated based on a 'football management' style simulation model." By virtue of allowing the ability to teleport around the course, it was not possible to simulate the cars circulating the track 100% of the time.
The post addresses a few other issues. The numerous pit stop problems such as being forced to wait in the pit or even becoming stuck there are being investigated and they are attempting to duplicate them so a fix can be made. Other problems like AI cars making abrupt track resets and incorrect advice from your race engineer appear to be simple glitches that will be addressed in the patch. No new word was given on when that will arrive, though, beyond as soon as possible.
I really don't mind if the quali and practice sessions are not calculated on track. I just WANT THEM TO GET OUT OF MY WAY when I am on my flying lap, and when lapping them in races.
Out of all the bugs I have experienced, this is really the main issue. Well that, and getting penalties for AI drivers crashing into me.
Oh and I'm not sure, but it sure seems like the fuel consumption isn't calculated properly. I always post my fastest times right when the option tires are in best condition. I even tried running them right at the end of the race - fresh option tires and a nearly empty fuel tank, I should be setting lap records. But no, pretty much within a second of my best times. Even for a non pro like myself, it shouldn't be possible to have slower lap times on my favourite track with 200 lbs less fuel on board.
OK so THOSE are the annoying bugs.
Exactly! I shouldn't be competing with a driver while on my fast lap and they just came out of the pits!
