I once shifted a fully restored U/C for a friend with my L/L Chev. It was sitting in his workshop at a slight angle to the doorway I reversed the truck through to load it up. He attempted to align it by pulling the steering wheel full right to lock the track on that side then gave it a few revs as he eased the clutch out intending to slew the vehicle on the spot. All that happened was the L/H track whizzed around. The carrier never moved.
The same thing happened again when we had it loaded and wanted to straighten it up on the truck. The track simply whizzed around on the steel rub strips. We couldn't get the thing to move itself.
A more serious event took place a couple of days later when the owner attempted to move the carrier whilst on display at a Rats of Tobruk reunion. The thread stripped off the rear end of the long R/H brake rod and the equaliser linkage meant that all pedal travel was used up pulling the disconnected rod= no brakes!!! The vehicle was in neutral and was rolling backwards toward a group of picnickers sitting on the lawn. The driver slammed the transmission into gear and I flicked the ignition off. Disaster averted!
The reason for the thread stripping was that he had replaced the rusted remnants with metric rod instead of imperial and with the rod being undersize only a partial thread was cut.
When we figured out what had happened we realised that steering left would apply the left brake and knowing that were able to shift the vehicle safely under its own power after taking every precaution.
