Doesn’t a helicopter serve these needs? I think the problem is there isn’t a market for it yet. There is Blade in NYC and LA but it’s closer to 10x the price. I think the cost could be a lot lower if there was higher demand.
I think there doesn’t need to be new tech to make this work. Helicopters are safe and reliable, but are out of reach financially for most. I don’t see how drones or multirotor would be able to compete on price for a very long time.
