Ya it seems like risk profile isn't very clear, nor do major risks have sufficient mitigations.

I feel like the easier place to start is a low-speed automated cargo delivery system that runs on pre-defined flight paths and only in certain weather conditions. Even then you're dealing with pretty decent risk profile given the failure mode of anything flying is rather dangerous.

I'm not against flying things in cities per se, just want to see the discussion go more like 1) flying things are good for X Y Z reasons, 2) major issues to address before we get there include A B C, 3) here's how we're solving those to unlock this new opportunity. Maybe that discussion is happening in other places, but I'd love to see these safety factors better addressed by anyone building these types of things, else it doesn't build much confidence in the viability of the company.

The safety system has to be integral with initial design and it is. Before these are used in urban environments the machine must be able to set itself down safely regardless of the failure. That is possible.

Cool, I'd love to see the specifics. I imagine it'd be impressive and worthy of showing off.
