The difference with the helicopter is that you can approach it safely from almost any angle to board/deboard, just don't approach from the tail, whereas this flying car thing has a ring of death all the way around the outside. And having the option of leaving the thing running has some advantages too. I'm just not buying that this design solves any problems. At most it miiiight be a cheaper helicopter, but right now, it looks substantially less capable than helicopters too, and it seems like its failure mode is worse (helicopters can survivably land through autorotation even with a full loss of power; N-copters can't). So I'm not really seeing the benefits of this design.
