This is a video of a Ford Mondeo in Santa Catarina,Brazil that was modified with a lowerable fifth wheel in the rear so it can easily pivot its way in and out of parallel parking spots. whether you're not familiar with the concept (which has actually existed in several different forms since the 1950's), I included another video of a car with a similar device viewed from a much better angle that makes it crystal clear what's going on. Now whether only I'd had a car equipped with this during the parallel parking portion of my driving test, or perhaps I wouldn't absorb failed three times. "You hit every single cone." Whatever,that should absorb only been like a couple point deduction. "And backed over the test administrator." I think that was the real kicker.
Keep going for the videos.
