N4 Major Physics Problem or ?????

I just picked up and installed the game.  I am using an analog wheel
and pedals, Simulation model, Linear steering and no cheats besides
automatic clutch.  I also tried several different steering gear
settings (garage).

The problem is that once the car begins to oversteer due to throttle
application, no amount of opposite lock has any effect whatsoever.
Clearly in a car with race tires you should be able to recover
completely from throttle oversteer (not lift throttle oversteer) at
low speeds.  

The effect of this is that as you are driving around a road course if
you make a mistake you cannot recover.  This seems like such an
obvious mistake that it is hard to believe it slipped into the game.
I would love to hear that there is a setting I have missed which will
put the handling back where it should be.

I have had one friend that also has the game confirm that he is seeing
the same behavior.

Thanks,
Eric Fesler

What happens if you engage the clutch when the spin starts?  Like GPL, even
if you let off the gas, there is still a whack of HP flowing to the rear
wheels under these circumstances (i.e., immediately following
throttle-induced oversteer).  (I don't have my copy of N4 yet, but the same
thing will happen in GPL, so I am extrapolating.)

Try to use less than full throttle when exiting the corners.  You can't
expect to throw all that HP onto the road at once and easily drive away!
Once you start spinning the rear tires, you have lost most grip in the rear
end so it will oversteer!  If you use less throttle, that lets you
accelerate without spinning the tires, so you keep the grip in the rear, and
accelerate faster...or is using partial throttle a new concept to you?

More over, if i remember correctly, the WC cars have 2 tons weight !!
And GPL cars have avg. 600 kg ! That's a LOT of inertia .

IIRC one of the motor simulation sites (BlackHole?) has a review by a Nascar
driver of a Nascar sim who ststes that, in real life,  once the car is
beyond (I think) 15 degrees, it is uncatchable.  Maybe someone else can be
less vague than me!

Oh no! IRL Nascars have a canned spin routine built in ;-)

I don't know about this guy, but I've been to a race. They're fun!! I am
flying out to Vegas in March for the Winston Cup race. That will be fun,
too.

That's perfectly normal Eric.  Those Winston Cup cars weight over 2 tons,
you can't expect (even if you are on banking) to catch a car easily as that,
even at low speeds.  I suggest you perhaps tap the brakes a little

no they dont weigh over 2 tons. If you dont think they can be corrected in
real life racing, you have not watched the career of Dale Earnhardt SR

It could be accurate.

Clearly??? Clearly you need less throttle.

It is certainly possible.

Try using less throttle.

One last thing. Duh :-)

Sorry, in France, Nascar is not very popular, and the last time i saw
nascar on Eurosport they say that they weighed 1.8t, Engine was 6L , 4
cylinders, and about 400bhp ... I will be pleased to know the new values !
And i don't say that you can't correct it but it is very more difficult than
a 1967 F1 car because of the weight. So it's a compliment for Nascar
drivers, even if IMO F1 pilots are better drivers ... but anyway we can't
compare those two style of driving.

You've probably seen it already, but check the post from rreved where
he qoutes Dale Earnhard jr. who sais 3400 pound stock car. That's
approximately 1.7 - 1.8 tonnes :)

Depends on what kind of ton your talking about.  Anyway I think we get the
point that a WC is "heavy".  So often people loose the point and nitpick.

let summurise this,

 1.7t / 700 bhp / 8 cylinders ( flat ? twin ?  )
Tyres  : slick ? ... not very wide anyway

Well, now we can tell that it's difficult to correct a slide
so Nascar 4 IS accurate :o)

CQFD !
that means in French " That what it needs to be demonstrated " :o)
