The more you look into it the more you realise it is nothing more than a gimmick and not much worth to a team .There are strong simualtion tools around to predict car behaviour and I´d think this is really enough ...getting the driver into the loop is a nice idea but it would only be a help if it was replicating everything realistic which is just way too elaborate.
Thinking again with the currrent steeringwheels and DRS ,KERS and what have you it might be useful to memorize the routines so you don´t have to divert your attention to things like DRS in a hot lap and just release kers in the perfect moment...but that´s it really.
As a quick handcalculation reveals .high sustained cornering gs and breaking are not going to be felt in simulators as the effort is remarkable...
