It is interesting to note that most of these videos are from outside the country. I wonder they do not use any professional service and just use makeshift/whoever they can find type of deal. Another video I watched where a car is set upright only to roll away to ditch - kept me wondering why in world would they not lock the brakes or something before going through all that trouble. I am no engineer, but it would make sense to me to have some counter weight/pull from the other side to stabilize the rig when setting it up right.
