Exactly. They also don't teach you to trust your instruments when your
middle ear is trying to convince you that you are flying straight and level
when in fact you are in a descending left spiral. You just don't get the
feedback in your loungeroom.
The best sims in the world can't duplicate that experience, but they are at
least enough to give you an idea. I know that people have been airsick in
the P3 sim at RAAF Edinburgh when they have turbulence dialled in. It's
fairly convincing for most things.
They can't quite duplicate the separation of the wing leading edge when the
aircraft is overstressed, but they can at least reproduce the conditions.
(Real Orions are known to do that, we lost one at Cocos Island a year or two
back that way, not a fault of the aircraft, it was being, ahem, mishandled
at the time.)

Suspension of disbelief is fairly vital if the simulator experience is to
have much usefullness when related to the real world. It's got to feel real
enough to make you forget it's not an aeroplane, and it's got to behave like
the real aeroplane as much as possible without antigravity assistance.
