Well, at least I have a diploma and am allowed to use the academic 
degree 'Dipl. Ing.'.

But anyhow:

would you really allow constant velocity along 'any polygonal line'??????

To me this is blatant nonsense, because acceleration depends on the 
radius of curvature of the path and in a sharp corner with zero radius 
the acceleration would be infinite.
