I've been asked this question a few times today so I will answer it the best I can.
StabiliTrak is a General Motors system in vehicles that assists the vehicle in maintaining the driver’s intended path by applying a brake force at any corner of the vehicle independent of the driver’s use of the brake pedal. StabiliTrak uses an accelerator pedal position sensor, a brake master cylinder pressure sensor and a steering wheel angle sensor as inputs to interpret the driver’s desired path and whether to accelerate or decelerate the vehicle. StabiliTrak also uses these sensors plus a lateral accelerometer and yaw rate sensor to determine the vehicle’s actual path. If the difference between the driver’s desired path and the vehicle’s actual path becomes great enough, StabiliTrak takes appropriate action to assist the driver with maintaining the desired path. If the vehicle begins to “snowplow,” or understeer, StabiliTrak applies the inside rear brake to help turn the vehicle. If the vehicle begins to fishtail, or oversteer, StabiliTrak applies the outside front brake to straighten the vehicle. StabiliTrak is integrated with the traction control and ABS systems.
In other words "Yes" "soon the vehicles will be driving themselves"
This is such a great safety feature,(that Buick has had since the early 1990's, now the government has set a standard for 2014 for all passenger vehicles sold in the US to get this great highly advanced safety system- Now, Most other manufactures have some sort of stability control system also.
