Ernie, not wanting to use aids is not about being so called hard core, it is about the pleasure, in a well designed SIM, to have control over the car you are pretending to drive. All aids somehow disconnect you from feeling ( with a wheel) how the car reacts.
Aids have good reason to be there as not everyone wants that direct connection, as it is also more demanding and might take away from the fun of it for some.
As long as the aids can be set off, no "hard core" driver will ever complain, to each his own.
About the real version having an aid or an other, very often is does not mean much, because the corresponding aids in most sim do not react the same as the aids works IRL.
So more often then not, you have a more realistic, immersive, experience with all aids off.
