You must have one hell of a heavy finger then, as it certainly doesn't spin me instantly I apply the accelerator.
Utter and complete nonsense.
Lets take a look at the real world then shall we.
First off a true definition of what causes oversteer, its when the rear tyres slip angle is greater than that of the front tyres. The bigger the difference the greater degree of oversteer we are dealing with (and the opposite is true of understeer).
The two causes of slip in tyres are from rotational forces (acceleration or deceleration) and steering input. The greater these are the greater the slip will be, so with oversteer being a case in which the rear slip is greater than the front slip its both locigal and correct the oversteer can and does occur when you are not at full lock.
In fact all other factors being equal the less steering lock you have on (as long as you have some) the greater you have a chance of developing oversteer. Full steering lock can often result in understeer rather than oversteer.
Now lets look at the other claim, and take a car with the engine at 3,900 rpm, at which speed this car produces 295 ft/lbs of torque. Its in second gear, which has a ratio of 2.369, the car also has a final drive ratio of 3.85, that will give us an at the driven (rear) wheels torque figure of approx 2,690 lbs.
Now given that this car weighs 3,649lbs and has a static distribution of 51.20%, that would mean under acceleration that we could expect to see 2,000lbs (given load transfer to the rear under acceleration and being
very generous) on the rear wheels (I am using a rough tyre/road 'co-ef of friction' of 1.0 here, truth be told on public road tarmac it would likely be less).
The problem we have is that is less than the 2,690 lbs of torque it has to deal with. So at an engine speed that could be quite easily be achieved at part throttle and being stupidly generous in regard to both load transfer and tyre/road grip levels, its quite easy to see that its more than possible to do in the real world.
The car in question here in case anyone failed to guess is of course the very M3 that its been claimed would not be able to do this in the real world.
Hell I can get the back of my 320i to step out in second gear on dry tarmac with part throttle and without full lock, if that can do it with a 2.0 straight 4 then its not much of a leap to see the M3 doing it (and the figures above clearly show it can be done).
Now don't get me wrong I am not claiming that GT5

is perfect (in fact you will notice this is the first time I have referred to it), but please don't make statements about what is definitively true in the real world unless you can actually put some info behind it.
