300km/h and 300km range means 1hr endurance. That means it probably cannot be used at all for paid flights in the USA. Reserves required are greater than that (enough fuel to fly to destination, to alternate, and then 45 mins).
And for a VTOL plane that can do a descent as slow as they've shown with their two seater, getting low enough to find them is far less of an issue.
But the other thing I'd forgotten is that if it were to run out mid air or you can't find anywhere else: the two seater at least had a whole vehicle parachute, and it's built to be water resistant.

The gist: max. 5 PAX, max 2,000 kg VTOl craft requires an own set of certification criteria as neither aircraft nor rotorcraft requirements are feasible.
No idea about the current small rotorcraft certification requirements so.
And at least regulations are worked on in advance. That Airbus is also working on a similar project might help to speed things up with EASA as well. Just what that means for Lilium remains to be seen.
If you're going to make VTOL exceptions, you still can't just punt and say put it down anywhere. What if you're over LA and there's no clear spot for miles? Over water? In instrument conditions (necessary for scheduled flights, because weather) and you can't see below you?
Not saying we shouldn't amend the FARs for new aircraft types, but there's some thinking that needs to go into them.
IMC seems to mean Instrument meteorological conditions
