    @todo
    #due to the current turn function, the left turn bcp is exactly the same cost as pcb, a right turn. The right turn should be way faster,though
    #for that reason we cannot distinguish between driving clockwise through the circle or counter-clockwise. Until this is improved, this case here
    #has to remain as todo (see #https://github.com/Project-OSRM/osrm-backend/pull/2849)
