With a 20 minute flight time (and is that with any safety margin remaining? Doesn’t say.) at ~60mph I can only make a 10 mile round trip. 20 miles of each landing spot has a charger (and I doubt there’s weight budget to carry a decent charger with me). It’s a very cool kit for hobbyists but there are very few missions this can fly with utility.

Perfect for beating London traffic

I saw that video some days ago and thought "that would be a nifty way to get to work and back" ... 12 minutes flight time would actually allow that for me ... but not for a lot of others.

12 minutes endurance is absolute madness to any pilot. No way to fly this thing within the current regulations. A fuel powered aircraft needs to land with a legal minimum fuel reserve of 30 minutes when flying visually (good weather only), in worse weather it's 45 minutes + the time it takes to get to an alternate airport in case of problems at the destination. So usually 1 to 1.5 hour of reserve/alternate fuel on to…

Does this rule also apply to helicopters and other VTOL aircrafts? The alternate airport in this case might be a field or parking lot 100 meters away.

I wonder why the rotors are positioned so low. Should a propeller get fractured, the splinters would hit the pilot's chest and neck. OTOH putting the propellers above would change the shape and thus the aesthetics seriously.

At least small planes in europe (CS-23) aren't allowed to have humans within an (iirc ~15 degree) cone of them. This approach here seems to be done with no regards to such regulatory (and well-meant) requirements.

Sweden is very much "in Europe" and according to the company it's legal to fly it there.

Doesn't matter until there's a breakthrough with battery energy density. Any electric VTOL aircraft capable of carrying humans is limited to less than 50 miles range.

It could certainly be useful as a recreational vehicle though.

Or as the cool gimmick in the next James Bond movie, complete with sponsorship, so that it could attract interest and fuel the development of better aircraft in the future.

In good weather a helicopter is allowed to reduce it to 20 minutes.

In bad weather the alternate must be an airport with the facilities to conduct an instrument landing, so definitely not just a parking lot. And the forecasted weather at that airport needs to be good enough from 1 hour before until 1 hour after the expected arrival. "Good enough" is defined stricter for helicopters than for airplanes.

That depends under which class the aircraft will be certified, depsite it being electric I could image that it falls under the ultra-light class (I'd have to look up the exact Name under EASA so).

EASA doesn't have rules for ultra- and microlight aircraft, they're only in national regulations. So then it depends on what the country you're in decides.

But even if you're allowed to fly with only minutes of fuel reserve. The big question is whether you should want to. When you're in a more basic aircraft, that didn't go through all the certification requirements that other aircraft go through, it would not be a great idea to skip all kinds of safety practices like fuel and alternate planning just because you're not legally forced to do it. You're then just increasing risks more and more, while this thing is marketed to non-pilot buyers that may not even fully understand the risks.

The giant balls of whoever flies one of the things would shield the head and neck area.

You might want to meet some football players/wrestlers/gymnasts etc before you tell someone to lose some pounds, just based on weight alone

Football players, sure, and a bunch of other kinds of athletes ... But aren't gymnasts typically relatively light?

Yes, gymnasts are typically very lean. Source: I used to be one, though I'm not particularly lean anymore sadly.
