J4D wroteWhat they are using in the youtube video that you shared is complex, big, over engineered and not perfectly real. in a car you would not be jumping around like this.
I don't think that it is over engineered, and the simulator it is very real... the jumping is to simulate the
G-force...
In reality when a car slows its speed suddenly, the driver moves forward but the seatbelt prevents him from crushing the car front glass... in the simulator, at sudden car deceleration, the seat is inclined rapidly to the front, so the driver feels as if he is attracted forwardly and the seatbelt prevented him from crushing the front glass (which is the screen).
The driver in the simulator will not perceive the sudden inclination as an inclination, because the screen is inclined with him (the screen is the outer world, and it is his frame of reference)... only us (the outer observer) will see it as an inclination...
