Kenny I'd follow Lakedude's advice about matching the engine speed to your car speed.
I usually rev to around 1500K- 2K RPM as I put it back into Drive.

What ever you do, don't take it "one step further" in that situation and reboot the car.
The reason is that when you restart even in Neutral going ~70MPH will cause a terrible jerk in the drive system.

Efficient drivers do it better.
