Hi Vi,
it is another, somewhat redundant degree of freedom...there was a project a few
years ago on this list. I brought up this issue once and juergen cleared me up
on that ;-)
i have my reservations whether one can safely control a double pivot setup.
Maybe, if you link the two together, so you end up with connected steering?
