Personal view: given than BRS landings seem to be quite hard, the thought
of flying something to which the only way out of any type of emergency is
"fire the BRS" is not reassuring.

I think you do not have a good idea of "quite hard" - BRS systems in
certified aircraft like the Cirrus and Phoenix are sized to land the
aircraft slowly enough to avoid injury most of the time.

I think with the Volocopter - we'll have to wait to see if their testing
backs up their claim of "gently", but it certainly seems achievable,
given the lower max speeds. I'm sure they have a number of ways to deal
with the "dead zone" as you obviously need the aircraft to be moving
through the air for a parachute to work. I'm guessing it would not be
allowed to deploy when hovering (and you don't need it then, either),
perhaps by automatic means.
