how to make fast moving controller go all the way to linear points?(curvy8)

[hawken]

When using a linear interpolation shape, such as a square, a fast moving spline controller won't move right to the points in the spline. Instead it curves near the point and goes straight again.

Is it possible to make the spline controller move right up to the CP and then change direction when moving at a high speed?

I put a particle emitter on a spline controller and move the spline controller at speed 22 absolute, on a 3x3 rectangle.
