The Taurus I'm virtually driving is very real, but the car is bolted solidly to the flat floor of a spherical pod. The roof overhead is about the size of a military early-warning radome and is made from the same material. Eight huge hydraulic jacks that support the pod some 20 feet in the air generate the sensation of motion. The hydraulics are quick acting, making short, fast, lateral moves, then tilting the pod smoothly. The occupants inside feel the force of gravity simulating acceleration, braking, and turning. To observers on the outside, the pod's gyrations make it look like some giant insect learning the chicken dance. But seated inside, with a computerized view of the road coming at you and the bobbing dome contributing the physical sensations, it feels like you are driving a real car on a real road.
