Yes, we can debate the specs but AFAIK it's the most advanced fixed (although folding) wing car/aircraft hybrid. I haven't seen video of a test flight that's not barely out of ground effect, though.

Over the years there have been some buggy/parasail hybrids e.g. http://fly-skyrunner.com/ . Those actually have some appeal for off-road/remote use. You could fly over otherwise impassable terrain e.g. swamps, rocks/crags etc.
