Your saying that when the car understeers it is turning just as hard as it was before? I hardly find that true about this game at all.
But even the worst balanced ABS-equipped cars, even those which I've gotten to go sideways just by looking at them funny, were supremely well-mannered, even when trail-braked on the autocross portion of the test.
ABS prevents wheel lock-up. And oversteer under braking requires either the rear end to jack up and slide or a rear wheel to lock up and slide.
Either situation will trigger ABS.
A locked rear wheel will obviously trigger ABS.
When you have a rear wheel up in the air, the ABS will chatter like an insane monkey because a rear wheel is locked in this situation, too.
This is one of the biggest dynamic flaws of the new Mazda2. The rear end is light and the rear drum brakes lock too easily as you plow into a corner. Otherwise, it's a peach, and you can initiate a drift with a good throttle-lift and a Scandinavian flick. Try the same with a little trail-braking and it'll merely carve an understeery line through.
Thus: trail-braking into corners on most modern cars (Yaris included) with the brakes full-on will not itself initiate oversteer. It requires a flick and/or lift-off.
With no ABS... well... I just recently did a 52-car mega-test which included some 244 hard stops. And the most interesting of those were on vehicles with no ABS... jump on the brakes in a straight line and you can slew out pre-e-e-etty far sideways...
Thank you.
I never expected an extravagant welcome party, but I was beginning to think I'd simply blended in with the scenery.That's good to hear, and I'm glad I'm not alone in knowing the severity of this effect in the real world. It was only a few months ago that it "clicked" for me that this particular phenomenon plays a major role in separating the "true" sims from the "wannabes." Even ample simulation of power oversteer can't mask it.
First, let me paint a big red bullseye on my forehead. Second, ouch.Scaff, thanks for your input here, i'm learning just from your posts
If you've never tried it, I always highly recommend Live for Speed (for the PC) for its extremely detailed physics, but in this case I'd like to point out that it allows you to tweak the sense of speed via the "Field of View" option. You can set it anywhere from "molasses" to "Warp 9."
A quick note, it's never really the "physics" of each car that game developers have to worry about, even when making an encyclopedic, GT-style car game. There's only ever one physics engine (possibly another if there's something like a drift mode that behaves differently). The differences between the cars lie in the stored values (center of gravity, spring and shock rates, torque curve, etc.) that are plugged into that physics engine by the CPU.
The question, then, becomes whether PD had the time to vigorously research each car and generate accurate data on each of the cars. Which kinda points toward the whole "blank slate" suspension setup issue others are complaining about in this very same thread.
Or if you're driving an MX-5... that bloody little thing oversteers all the time...
That's mainly down to what is know as the Polar Moment of Inertia, the lower it is the better. Have a read oof the following....
Have you had much track time in the MX5?
I have to say that I agree with you on this.
Well... it's likely that under light braking, you've got enough weight transfer to initiate oversteer, but not enough braking force to cause a momentary lock that starts the ABS. You might try adjusting the balance to see what works.
Mind you, GT5's ABS isn't perfect... if it's anything like GT4 or GT5P ABS, it's a bit too aggressive, not letting any lock-up at all even at the lowest settings (some real-life systems allow a tiny bit of lock before chiming in... or allow a lot of lock at the rear end before turning on). It may take some brake bias tuning and ABS fiddling to get the car completely true to life.
