How would heavy rain affect your overall stopping distance?

Explanation: In heavy rain, the road will be wet and there may be pooling surface water. This will reduce the grip the tyres have on the road and will at least double the distance it takes to stop. Take this increased stopping distance into account while driving. Double the separation distance you'd leave in dry conditions.
