Fuel has the same problem in aeroplanes, and is a failure that is really quite avoidable. Don't run out.
Only real difference being your takeoff and landing weights are the same.
For a small aircraft tho, that is negligible I suppose. On bigger units would need consideration.

Actually makes it really simple.
Big aircraft burn more fuel the heavier they are, so pilots are always being pushed to carry less fuel - which is stressful. Trying to balance commercial pressures and safety, especially with weather considerations enroute or at destination.
Having MLDG weight = MTOW is perfect. No holding to burn off fuel, or jettison (if fitted) in the event of a diversion or return to landing due to a failure.
Pilot's salaries would be cut bigtime without all of that stuff to work out and judgement calls to make. Not that anybody has a job anymore, due to covid. Very glad that I am out of the commercial stuff.
We are a long way from large aircraft being electric, I suspect, so all a bit pie in the sky rather than battery in the sky but I would love to see small electric craft very soon.
One thing that I should have added to my reply to @nzzp about safety - that machine should be able to auto-rotate like a helicopter.
"The longest autorotation in history was performed by Jean Boulet in 1972 when he reached a record altitude of 12,440 m (40,814 ft) in an Aérospatiale SA 315B Lama. Because of a −63 °C (−81.4 °F) temperature at that altitude, as soon as he reduced power the engine flamed out and could not be restarted. By using autorotation he was able to land the aircraft safely."Otherwise something like I have in my wee plane:

Exactly what I was thinking - the ultimate emergency fallback IF the VTOL rotation works
You'd think tho that on power loss, all servos would release and allow the nacelles to point upward.

Yep, exactly.
I don't know for sure, but I assume that the nacelles would be held by positive hydraulic pressure in the more horizontal position so a failure would default in the vertical mode.It may need some airspeed to make it all work. There could be a "dead man's curve" like a chopper with H-V (height / velocity) before an auto is possible, but the reliability of electricity and motors makes it a very unlikely event.
Translational lift comes into it too and I don't know enough about tilt rotor craft (in this case VTOL) to know how they overcome time delays for tilt, but that machine has two fixed forward facing conventional motors as well so the H-V would seem to have most contingencies engineered into it and the graph would have a small red zone.

You better not be talking about that bullshit 90-degree delay law for common-sense in helicopters.
That shit makes me wild. Like... boats going faster than the wind, bullshit.
Everybody knows, if you want a helicopter to turn left, you'd have maximum tilt on rotors on the right-hand-side, minimum on the left. Not maximum 90° BEFORE it gets to the right hand side. That's fucked. AC75 fucked. -

Thinking about one of these for the wife:
https://www.ford.com/suvs/mach-e/I think that I have mentioned that our roads are unsealed shit (several times, possibly hundreds) - so the AWD. Lose a few kms range but still would do us nicely.
Wife is very keen on that machine so I have a balance:
I still read "Jobby" when I see that so it may well be be a turd.
The only thing wrong with thatFord is the name. It's not a Mustang, and drags down real Mustangs!
They are pushing the new Audi E-Tron GT's here. Sister car to the Taycan, and in my view, much better for it (wheel design aside). This looks stunning. Stunning price too

https://www.audi.co.uk/e-tron-gt.htmlAgreed on the Ford and the name, trying to make it something it's not just with the branding. Still seems to be pretty good though.
We are getting heaps of the Audi E-Tron GT ads as well, and yes the wheels look awful but you probably get a choice. Looks like my father will get one as his current e-Tron is a huge car for what he needs. That was a hefty price to match the size of the car.

@catogrande I think the tesla 3 long range is about 300 miles? Arguably not the best but not too bad.
What would worry me about Teslas:
-the build quality (improved I hear)
-parts and service
-the wife driving it (she doesn't like complex cars)
-oh and me too, I doubt it is a car I can tinker around with at home.. -

-oh and me too, I doubt it is a car I can tinker around with at home..300 miles is pretty good but it’s not just that. How long to re-charge the thing? Not that I’m bashing e cars, I’ve come to agree that it is likely to be the way forward but that it will take many more steps in feasibility to get there. It’s the future but not yet the answer.

@catogrande friend of mine has a leaf in the states, it charges over nights and never has any dramas, very reliable (but in adverse climates it does not have the best battery tech).
tesla 3: https://pod-point.com/guides/vehicles/tesla/2021/model-3
The Kias, new Hyundais and Nissans are getting close to 300 miles and the next iteration of battery technology should be a giant step forward.
Problems: fighting over charging stations, paying extra for quicker charging at home, crazy taxes (read: parts of Australia), depreciation, changing the battery... -

Some of the Chinese EV companies are exploring battery swapping stations to get around issues with slow charging
That sounds like a sensible stop gap measure. The elephant in the room though is battery disposal. Questions are already being asked about how green EVs really are. Energy is green but the hardware, for want of a better word, is another thing. Long way to go yet.

If it worked like swapa bottle gas, that'd be great

I agree. Jeremy Clarkson used to go on about how much environmental cost was associated with making those batteries

the energy used for rigs to drill oil is mindblowing.

How Toxic Is Your Car? | Trellis
The "new car smell" that has seeped into the public consciousness is the byproduct of poisonous chemicals used to manufacture automobiles. A new website lists the best and worst cars and urges automakers to make driving safer from the inside.
I expect future batteries to move away from lithium and already battery swapping is a thing in Asia but some Tesla are already prepared for it

I really thought by now battery swap stations would be everywhere.

That would require substantial engineering standardisation. Even in common platforms there'd be considerable difficulty I'd imagine with all the connections and whether the battery pack was a stressed member.
Given chemistry, it seems to me that there won't be a great leap forward in range vs battery charge rate and life so the reality would be buy a car that fulfils 95% of your yearly needs and rent a larger capacity (range) vehicle or take more time to get to your destination or fly...

@majorrage yes there are some major infrastructure issues still.
A problem is though if everyone swaps to electric by 2030-35 what happens to the old ICE cars... -
