but screws up turn 9 by overshooting the turn, then driving into the grass/sand. 
Yeah i've totally noticed this. My opinion is, that is a very tough corner. I'm personally used to going much faster down the hill, braking a tad, and then zooming thru turn 9....but you can't do that anymore...now you really gotta keep your speed low--even as you come down the hill. Kinda sucks, but i guess that's the way the real track has been re-done.
but yeah...the Ai used to screw up the corkscrew something mad! Now it tends to get the corkscrew okay
haha i was beginning to think that i was delusional and no one else had seen this because no one was replying
Agreed, in GT3 you can do that turn before that long uphill before the corkscrew at full blast, or minimal braking, with no side effects, but now you have to slow down to around 75-80MPH depending on car and tires. It was possible in GT to do Laguna Seca in 55 seconds or so in an F1, but I don't think it's that easy now.I think in GT3, the corkscrew didnt require you to turn TOO much, but now in GT4 you actually have to turn, otherwise you'd hit the dirt, like the actual circuit itself.
I still today, decide to cut the corners a bit, and zoom down, regardless of hitting a lot of little dirt. I've been doing this since GT2,
The track looks cleaner obviously in GT4, compared to GT3, but the track is more narrow, brighter, and much thinner curbing. yo are forced to do turn one in the thin road on the left now. 👎
Nope. NObody has seen this thread. It's in the invisible section of GT planet. We basically have our own little chat room.
Having stood and looked up at that turn in real life at Laguna Seca a couple of weekends ago, I can tell you why.
That turn is a lot, lot steeper than the game actually seems to represent it.
Although the steepness of descent in the Corkscrew is readily apparent in the game, it doesn't convey the true openess of the runoff area, nor the massive descent that goes on as you pass through the turn and under the bridge there.
It's a downright nasty turn, with a deceptive turn-in point and a steep downhill area where a tap on the brakes may seem enough, but really isn't, especially in some of GT4s Supercars & Race cars.
I'm surprised Jordan himself hasn't chipped in here yet, having experienced the real thing just a month or so ago!
To me it happens (either to my car if B-Spec is on or to any AI cars), especially if the cars are more powerful, in almost every lap.
If Bob's driving, I have to decrease the pace for that turn only (for example, if I'm on 5, I have to set the pace to 3) or he'll go out on that turn like a swiss clock
I have to nanny him through that turn every lap otherwise he falls so far back he starts getting lapped. I haven't found any particular correlation between his inability to negotiate this curve and the car he's driving at the time, though I also wouldn't rule out the possibility that his sandtrap fetish may have some root in my "I wonder what happens if I turn this knob?" approach to suspension tuning 
He was awful there in the FGT series.
