It is not, they had those 40 years ago when I took my drivers ed. The one difference is those were driven from a film instead of a PC, so the upgraded models could be better (in that the PC image on screen could actually react to the student's inputs).
They also were an extremely poor substitute for actually driving a real physical car on the actual roads. As in they were only a 1% simulation. Someone could train on them for years and still not really know how to drive.
Unless the company building it invests Disney level money into building a full on simulator like some of the Disney park rides (significantly driving up the expense) the simulators will always be a poor substitute. And, even with a simulator, the student eventually has to graduate to a real physical car, whereupon all the issues with 'new drivers' again rear their ugly head.
