43 restarts...

[Duke]

...is what it took to get a relatively clean race in the Extreme World Circuits event at Motegi. And that's after I finally gave up auditioning cars and just settled for a crappy 8 A-spec points in my well-used stock 88C-V.

I put about 90 miles on the car and never made it past lap 2 except on 3 of those 43 starts. Most times, I kept getting nailed into the sand by the AI because I had to brake 5 miles out of every turn. A few times, I nailed them into the sand because I only braked 4 miles out, and so I rear ended them when I came steaming into the turn, standing on the brakes and downshifting furiously to no avail.

About 30 restarts in, I realized that the reason the car would randomly hurl itself into the sand was that I had somehow switched to the B settings and so it still had full ASM on. I don't know how anybody drives with that crap at all. Even after I turned that off, it still took at least 10 more starts before I got a race that wasn't too dirty to accept.

Wow... You are determined... 💡

Duke, Is that you? Or someone has hacked you? Doesn't sound like you at all.

The World Circuits thing was kind of tough, so I had to bring out the Nissan R390 GT1 Road Car fully modded. That car can destroy an A.I. piloted Audi R8. Why would you restart a race 43 times?

We all know how bad the AI is, just get on with the race, and ignore them, or just go in front of them, turn around, and attack them.

The AI is unforgiving...

Heh, I would've slapped me silly if I had done the same mistake with the A and B settings. I hate ASM (Ain't Steering Mate) as well. Anybody with a copy of GT4 should loathe it with a passion by now.

As far as having clean races goes, you're hardly ever going to have a realistic simulated race in 'the 'real driving simulator'. I mostly put in hot laps nowadays, but I do so in track events to practice passing as well, but it's painfully obvious that the AI runs its 5 cars like a train on rails. Even if they had peripheral vision they're set to run one specific line, so they don't give room to each other, let alone the player. That, and the fact that AI acceleration and braking points are all predetermined depending on the track (sometimes erroneously such as in Duke's case) doesn't leave much room for clean realistic racing.

Also, by looking at the way the AI passes, you can tell the other cars can only see about 6 feet in front of them. If they come up on you at say 7-8 mph faster than your speed they generally steer around you in one fluent motion. At 20-25 mph faster than you, they slam the brakes so they don't hit you, then try to pass. If they come up at 50+ mph they'll just slam into you since they can't react fast enough.

By now I'm so disappointed in the lack of realistic racing of GT4 that I can go so far as to say that I'd rather have no Ferrari in GT5 but Artificial Intelligence, than have Ferrari but Artificial Ignorance, which is all we've seen from the GT series since the beginning.

FGT was my friend at Motegi. 88C-V, 2J, 787B, all failed me, both A and B-Spec. But the FGT gave me victory when I thought all hope was lost.

Besides, Motegi is an F1 circuit, so it isn't technically cheating

I have yet to use the B and C settings...I miss GT3 in which you could actually save & label your settings for each car/track as a separate file (i.e., Ruf 3400S--Cote d'Azur).

That being said...I restarted my game multiple times to get a challenging line-up of cars in the 1000 Miles event! This means I would reset the race, look at the ai cars, compare their respective power & weight, and then do a few laps at Nurburging. My goal was to have race in which I wouldn't get bored; unfortunately it took perhaps 3 hours before I found the race I wanted!

In forza (I mean the first one, I havent got a 360 ) you had Ferrari's and decent enough ai, and even if you did hate the AI you could just go on live.

...Sigh.
