When I am driving downhill, can I put the car in neutral to save petrol?

Explanation
To circulate in neutral is not correct neither for safety nor for fuel saving. When in neutral, the engine idles (necessary consumption to avoid stalling), so it does consume fuel.
On the other hand, in neutral we can lose control of the vehicle because it will be more difficult to brake it.
The right thing to do when going down slopes is to drive with low gears and without accelerating, so the engine helps us to hold the car and also we do not consume any fuel.
