They might be dead regarding your car but still have a charge.

Deep cycle car batteries a few times and they truly are dead.

You can read that on wikipedia btw. or make a pilot or sailing license, it is one of the basics you learn in the first lessons: how to take care about the battery as you need it for the radio etc.

Obviously I have not,

But I have been in the Alpes at greater hights in a T-shirt.
The temperature is irrelevant (because it is air temperature), relevant is sun and wind.

As long as you are walking and carrying something it does not really matter ... unless you are in a snow storm with real minus degrees (C).

The parent is just an idiot, or one of the most unhealthy persons on /.

No idea what you exactly want to say.

However:
* first someone established the theory
* then it was interesting enough that minimum 3 groups on the planet tried to build a devise according to that theory
* the three groups we know about are the scientists who dared to report: "the theory works!"

Now -- especially /. -- wich saddens me, is full with anti science idiots who claim to know why the drive can't work.

But two or three crackpots claim they have a warp drive, and everybody is lining up for their tickets for Alpha Centauri.

The story is about the fact that this kind of drive is not a warp drive (as it was falsely reported in other news) but a very low thrust impulse drive. You will never beat the speed of light with it. However if you have 'enough' energy you can accelerate as long as you want, like with an ion or plasma drive but without the need of "fuel".

but explicitly excluding passengers taken expressly for monetary reward
That is ofc an exception as you need a special driving license anyway.
However if I decide to deliver parcels in a private car, I'm insured. And so are "third parties" as you name them.
My point was not my cargo ... not sure about that, did not check my policy regarding my cargo since decades.+
Good hint, perhaps I should check what that says.

If they "store" money for you in an account and enable you to transfer money to other accounts/banks: they are a bank.

No idea where you get your definition of a bank from.

Oh: you might be an american ...

In Europe Pay Pal is a bank, bank laws apply to them, otherwise they could not even hold accounts with other peoples money.

Normal car insurances in Europe cover commercial use.

Driving from home to work is, surprisingly, commercial, wow, a no brainer.

If I use my car to drive myself around or deliver Pizza or urgent mail or medicals: same insurance!

What the hell would be the difference for me or my car for what I use it regarding my liability towards anyone I (might) harm?

The driving license is split into two tests: theory and practical. Theory is about laws and rules, you have to pass a multiple choice test.
Failure rate is pretty high, something around 35 - 50% ... but that might be due to brain dead legislations which could be simplified and put down to more general more basic rules.
Practice tests vary greatly from driving school to driving school.
However there are ofc the MUST PASS tests: parking, U turning on a road, never pass a red light or stop sign, never take the right of way of another car or threaten a pedestrian.
Ofc the judge will also try to figure your general attention/awareness to the traffic etc.
But I guess failures are far below 50% ... I passes my car and my motorcycle license on first attempt.

OTOH I heard about a record in the USA where a woman needed something like 30+ attempts for the practical driving license.

20 years ago you had to make an so called "Idiots test" if you failed more than 3 times in any of the theory or practical tests.

However those got abolished for ordinary driving licenses, but not if you got caught 2x drunk (pretty low limit in most nations) while driving.

This was germany :D Now, next state of the EU?

They don't prove any such thing.
Of course they have, I suggest to google.
All they prove is that a bunch of questionable researchers claimed to measure a marginally significant effect
Your way of wording this is: libel.
What you consider marginal is your thing, others might disagree.
, and have been hyping the fuck out of it.
They don't. If they would you would know the names of the scientists and you and we would see them in TV regularly.
There actually is no hype.
Scientific openness is not equivalent credulously accepting the claims of every whacko and charlatain who makes a claim, just because it "hasn't been disproven".
How do you come to the idea that this is happening here?

We do know things about the world. Nothing is absolute in science, but some things come very, very close. Conservation of momentum is one of those.
Yes, it is. And the drive conserves momentum quite fine. Why do you claim it does not, when all the theories about how it works clearly state: it does???
