Safety and weather are covered by certification requirements. Those will be somewhere between small aircraft and helicopters with some eVTOL specifics. If it gets certified those bases are covered.

Privacy: Regulated airspace is your friend, plis why wait for one those if you can have your own drone for the price of one Lilium ticket.

Crime: Regulations also cover airport operations, so that base will be covered as well.

For me the question is not if those aircraft are goong to fly (they will if it os technically possible and people fund development), but rather whether there is an actual market for those big enough to make the manufactirers and operators viable businesses. The last qiestion is hard (IMHO impossible) to answer without getting them to market first.

There are certification requirements for both the aircraft and Ops Spec approvals for Part 135 (on-demand charter) operations. I can see that these would be certified to fly (and thus eligible for Part 91 (private) operations) far more easily than the more stringent requirements for Part 135 charter operations.

The FAA thinking is that you have greater understanding as a passenger on a Part 91 operation and are better able to judge the risk yourself, whereas a Part 135 (charter) or Part 121 (scheduled airline) operation, the public cannot effectively judge the safety of the operation so the FAA holds them to a higher standard.

Single engine Part 135 is possible, but there's a large amount of focus on redundancy: https://www.aviationconsumer.com/industry-news/single-engine...
