When the nasty accidents start, their appeal will wane.The food processor octo-copters (rotor blade plane of rotation at testicle height) are the same as rap music. I'm sitting here gritting my teeth waiting for the whole fad to go away, and it just never does.
It will not go away, the media is exploiting the public for "where is my flying car?" craze. Same for investors, everybody wants to be the first to commercialize a flying car, taxi, VTOL or whatever, see big players as Uber, Joby and Lilium. The public want will be even more after this covid experience, not liking being stuck in traffic again after comfortably working from home for so long.The food processor octo-copters (rotor blade plane of rotation at testicle height) are the same as rap music.

This will never work for two reasons: You'll need runways at every mall, business and street ends so people can reach every endpoint in their little Cub. Think like residential air-parks expanded everywhere. It is not feasible. Second reason: using small airports in cities, you need to get there from your location and get from there to your final destination, and when using your personal car it's actually faster and cheaper to go directly with your car to the final destination if it's under 200-300 miles. What I'm saying is that transferring from one mode of transportation to another takes a lot of time and infrastructure, it is much better to have a single mode of transportation, 'door to door' directly.OR... you could just put back all of the thousands of small airports in cities around the world, that were removed by the greedy-assed real estate vermin to put 10 million cookie cutter shopping malls, and have a simple, low-cost, efficient little Cub sized airplane to commute in.
There are some fallacies here:Multicopters are a dead end for safety reasons. Fixed wing and helicopters can glide to their crash site. Total power failure is frequently survived. A multicopters will just fall. It's only way to limit impact speed is a BRS. They suck at low altitude.
Even if they could be made safe, giving Joe public flying cars for city use seems like a dreadful idea to me, way too many idiots out there. A fender bender in a car would be a lot more serious in the air.
With separate motors, controllers and batteries, the estimation is that there is less chance of total power loss (except emp, lightning strikes and other unforeseen conditions) Anyway, I'm not defending or saying that multi-copters are better, far from it, actually I think they are less efficient aerodynamically - see my previous post, but they could be equipped with BRS parachute. As proved by small fixed wing aircraft equipped with parachutes, safety and peace of mind increases, and usually helicopters, due to the large rotor cannot be provided with a parachute.Total power loss turns a multicopter into a brick, at any altitude. There are more things that can go wrong than a single motor failure. Fixed wing and helos can still glide. Yeah, options are limited, especially at low altitude. But there are at least options to choose from, or avoid. Hit the school, or pancake the playground?
Automotive airbags do it, so the basic technology already exists.It would be rather interesting watching the necessary size balloon getting inflated in very little time
