Under the asumption of locality, aceleration can be described by only two dimensions (+ time) instead of 3 dimensions (+ time). In spherical coordinates, I can describe the direction of the acceleration I'm suffering with two angles, and the radius R is of no use (!)

I'm a bit confused here. Can anybody please explain me what's wrong in this assumption?

You probably still need a third angle, AND the radius-vector, to calculate absolutely all derivatives.
