Yes, but the fact remains that the level of shaking is downright silly. Even with the F1 car, it's not normal. I've compared with watching real cars on tv, and it just doesn't make sense.
I finally tested Werner's suggestion this morning (heard about it from someone 2 weeks ago), and it works for me - at least, when I drove my CLK GTR (currently my fastest car in my own savegame - but I will test the other fast cars with a 100% savegame later) and at 360km/h I could still feel the road, but the weird left-right shaking was gone. Now, I hadn't tested this car before this setting, so there's a small chance that this is the only car so far not to have this problem, but I highly doubt that.
Sorry to disagree with you Arwin, while the effect may not be perfectly replicated in GT4, its is realistic, first have a look at krazyboris's post, those are direct quotes from Derek Bell on driving the 956 at the 'ring.
I find it hard to believe that you can say that the effect is not realistic when compaired to an F1 car, just from watching the cars on TV. The steering ratio (lock to lock) on an F1 car is around 160 degrees, the type of correction we are talking about would be almost imposiable to see.
Now regarding set-up, toe angles also play a part here. The front tyres on a car will at speed adopt a slight toe out attitude, the greater the speed the greater the amount is a general rule of thumb.
Example 1 (and exagerated for clarity)

With the wheels adopting a toe out attitude if the car hits an imperfection in the road the car will naturally try and turn.
To increase the high speed stability of the car you could set a small amount of Toe in on the car, which would help with the high speed stability issues.

As you can see for the example above and with a lot of things in motorsport (and car setup in general) we have to make a compromise, as while Example two allows for more straight line stability, the toe in at rest and lower speed is going to make the car reluctant to turn.
In fact the majority of race cars are set up with a small amount of Toe out, which will help the cars ability to turn into a corner at lower speeds, but you will be making a sacrifice with the straight line stability of the car.
One of the reasons this is so alien to a lot of people is that road cars are never set up in this way (well as standard from the manufacturer); almost all road cars are set up with Toe in as standard. The loss of a sharper turn-in is a small sacrifice on a road car and as it promotes an initial handling balance of understeer is safer, as is the increase in straight line stability at speed.

Now while I will not dispute that GT4 has got the effect 100% acurate for every car in the game (after all it is just that - a game), to say that the effect is not realistic or that it should be left out is not something I can agree on.
I've said this in a number of posts before (and this is not directed at anyone in particular), the effect is realistic, if you don't like it then a number of solutions have been mentioned on this thread and others. After all its a game and you can play it in any way you want.
But (and this is a big but), do not say that PD have got this wrong. The effect may not be 100% accurate, but within the limits and confines of the game and platform its a damn good piece of work.
I have spent most of my working life in the motor industry (and at 34 thats over a decade) and have driven the majority of volume production cars on sale in the UK, in that time I have also had the pleasure to drive a good number of track and race cars. The difference between a road car and a true race car is massive, much more than a lot of people imagine.
Anyone who have also driven a true race preped car at speed will know that what you gain in initial turn in you generally lose in straight line stability; its almost impossible to increase one without losing the other.
Most race drivers will favour cornering ability over straight line stability, particularly as more and more modern race cars are using power steering systems. Remember a small gain in the corner generally translates to a bigger gain on the straight that follows.
