Yes, thats what I meant

But for such a "proof of power" a short attack which takes the service down once is enough, long attacks are not so common and actually require some work from the attacker

The actual interesting part about such an attack is not that something is down, but rather why someone would run it. A lot of DDoS originates from script kiddies, but such attacks are usually very short lived as attacks are expensive. So which actor would actually benefit from downing the Norwegian government?

Cool, but I don’t see the real benefit. Electronic trucks already work quite well, start at around 150k (vs. 150k for a retrofitted e trailer), and are afaik mostly limited by the charging infrastructure. If you now add a an electronic trailer to your diesel truck, you now also have to care about charging.

Yes, in Europe the legally required rest periods can already be used for efficient charging, but this is not an benefiting exclusiv to the trailers, but for general electronic trucking.
