I'm talking about input smoothing, which it seems you either missed or don't know what it is!
Point number 1, no they don't. Point number 2, I've already explained PC3 is more forgiving in this regard because of input smoothing.
Ok, so what is input smoothing?
First, you need to understand that a car will generate the maximum about of lateral grip when it actually exceeds it tyres slip angle limit by a small amount, the exact amount will vary depending on the tyre, but all tyres will do this. That is not a subject for debate, its a demonstrable, proven fact of vehicle dynamics and tyre physics.
As such all cornering on the limit will require constant corrections to keep at that optimum limit, and if you step over that limit then greater correction will be needed, until a point is reached where you will not be able to correct it. Any correction will need to involve applying the right amount of steering lock and throttle application. Once again these are not areas of debate, they are proven, demonstrable facts of vehicle dynamics and tyre physics.
See pages 13 to 75 of Milliken and Milliken's book, Race Car vehicle dynamics for citations on all of the above, and the following illustrates the point around slip angles rather well.

Now if a correction requires a steering input of X and a throttle input of Y to correct, then, in reality, you don't need to be exact with this and depending on the tyre you may well be able to get away with an overlap of say +/- 4% and still correct for it, with road tyres being more forgiving that slicks in general terms.
What input smoothing does is allow a greater, and more un-realistic range of error to still be seen as 'correct', let's say it allows correction overlaps of +/- 15% to still be seen as 'right'. Its not realistic, but it sure does feel great for most people. What its doing is smoothing out the errors in the input the user is making, making the driving model more forgiving and easy to get to grips with.
Ac to ACC categorically does not do this, PC3 in comparison to PC and PC2 does, and you can feel it.
Its why GTS and PC3 (and many other titles) feel so gamepad friendly, some even go so far as to start applying opposite lock for you, which PC3 does this with a gamepad even with all assist off. Its what Driveclub does, and funnily enough the same team that refined that area for Driveclub worked on PC3!
On a related topic you can see how far it can be taken with the steering and brake assists that you can complete a daily Rivals event with the throttle buried and only minor steering input.
