I don&#x27;t own one, but one possibility that springs to mind is, if you wanted, you could pack your garage with crap, leaving only a car-spaced hole.  (You know, like most people do, except for the hole.)  Then you use this feature to extract the car from the garage, without needing space to walk to it or open doors.<p>I&#x27;m only partially joking.  Our two-car garage is basically large enough for two average size cars and.. that&#x27;s about it.  We prioritize parking over junk-collection, but I could see the use.  Of course in the winter, in some climates at least, it removes one of the main benefits of the garage.<p>I guess one other benefit would be that you could always use your front door, whether walking or driving, so your shoes and stuff could all be in one place.  Might be a minor advantage for some.
