I don't think 4wd is a must have . But it does put two more driven wheels on the road.

Example would be in slippery conditions you avoid excessive braking pressure and would change down a gear to help the car slow. With 4WD you have four wheels taking the transmitted resistance through the drive train. This will bring you to a stop more quickly and with less brake pressure.

The opposite of this would be to knock the car into neutral and then try and stop. You would be completely reliant on the brakes.
