Driving in neutral

doesnt having it in gear increase rpm which can aid stopping/clamping force for braking?

being in gear increases rpm which increases the level of deceleration which will occur when you are not touching the accelerater - ie if youre in 2nd gear, say, at 40kmh, and you stop accelerating, you will slow down, but this effect will be much more pronounced if you were doing 80km/h in second gear. the faster the engine is spinning the more it will slow the car down when you are off throttle.
