What is does the Pre-Crash Seat Belts in the Tech package do?

 

The pre-crash seat belt tightens the seat belt to help restrain front seat occupants under emergency braking. This can help reduce the risk of injury when a collision occurs. Pre-crash seat belt will not be activated when:
-the brake pedal is not depressed
-the seat belt is not fastened
-the selector lever is in the reverse position
-the vehicle speed is under 10 MPH (15 km/h)

 

doesn't that already happen in the g35?

I wonder why they put it in the tech pack and not make it standard like in the g35.

 

This sounds similar to a "feature" on the IS350, which was more invasive than anything during aggressive driving. Does anybody know if the seat belts on the G37 act as annoyingly as the ones on the IS350?
