O RLY?
"In conventional fixed-wing aircraft, loss of an engine means you start gliding back to terra firma under the pilot’s control. In a helicopter, autorotation happens: the main rotor keeps turning thanks to wind pressure, providing enough lift to make a controlled descent to a safe landing."
...and in basically all modern "air taxi" prototypes which tend to be many-rotor aircraft, you won't even notice the loss of one of them if you have a bit of luck. At worst, you'll find it advisable to land as soon as possible, but plummeting is not on the table, as long as those devising the flight software were something other than monkeys with typewriters.
Multiple redundant power supplies would be expected and with four rotors you don't need them all to land in a reasonable manner. With six, you can even pretend nothing happened. And there are actual flying designs with eleventy billion smaller rotors - those would be basically indestructible short of dropping a bridge on them or flying them into a mountain.
ALL OF WHICH are inherently safer than either fixed-wing or rotary-wing aircraft having to snowflake down to the ground unpowered, trying to stay in the air very much like a brick doesn't, placing its hopes and prayers on the ability of the pilot to crash at least somewhat gracefully.
PS: ...also? Parachutes ARE a thing on these, and they deploy basically instantly. Look up "ballistic parachute" some day.
