...and also ?? ... makes the eliminations go-through faster ?
That is a misconception at many tracks. Since the driver now lifts 660 ft sooner, the car goes slower to the end and takes longer to get off the track.
If there is an early turn off, and the car stops fast enough to make it, then it can help. But that can be harder on the car braking system, and more dangerous than a more gradual braking to the end. So it depends...
I do believe the finish line speeds of the fast cars out there now-a-days is the primary reason when the track shut down area is not long enough.
