I find the Ehang particularly egregious, yes - it seems designed to chop people’s kneecaps and/or behead them.

The Volocopter, however, has the rotors above the vehicle, like a helicopter, and I don’t see how that is any more problematic than a helicopter.

Having ducted rotors might be another solution (should give higher efficiency, too, particularly when combined with counter rotating props).
