Thick pipe (not cable) from the back would not make sense. Most likely, they will charge up buffer batteries next to the EV first, then pump thousands of Amp into it.

I was wondering if my old wind up alarm clock system
could be used in cars, I had a toy car like that as a kid.
So wind up your car as the 'wind' station.
Could be from an electric motor or diesel or whatever.
Use a flywheel to get break energy back to wind it up again.
Would that work?

Many of the latest EV designs use 800V systems (eg Porsche, Kia/Hyundai). Previous generation were 400V mainly limited by the active devices in the inverters.
Larkin's calculation doesn't match the claim made in the article anyway.

No. But that is not what is claimed.
You are attempting to ridicule the article based on your own use case that is not realistic and not stated in the article.
I agree that the energy delivery rate of EV charging does not match that of liquid fuels but that doesn't mean it is impractical.
My car is limited to 150kW charging rate but that has had a negligible effect on my ten years of EV ownership.
There are very few cars that even require 100kWh to fully charge, the majority of long range EVs having batteries of 60-85 kWh.
Also that is not the way that roadside charging is used in general, EV users on road trips typically recharge when the car gets down to 10-20% and charge up to 70-80%.

Depends on what you like to do. I'd rather dremel FR4 than wear a tie

It works. Let a zillion crazy ideas happen and a few will be big.
In a more controlled economy, politicians predict the future and
allocate resources, and are almost always wrong.

Would that work?
From my copy of 'Theorie d'horlogerie' by Reymondin et al, the
amount of energy you can store in a spring depends on the maximum
allowable stress squared of the spring material, divided by its
Young modulus, and multiplied by the volume of the spring material.
It also says you can effectively get only about 17% of that value,
because you have to shape that spring in some way to allow you to
get the energy in and out.
So, the maximum stress of spring steel is of the order of 3 GPa
and its Young modulus is about 220 GPa. It has to fit inside a car,
so let's assume a spring of 0.5m^3. That's roughly 20MJ, which is
5.7kWh, of which only 1kWh is effectively useable. That's a scary >contraption, which moreover won't get you very far.
That's not going to work.
