Also in automobiles doors are expected to absorb the impact of side-collisions, which are very common.

The more one merelly thinks about it beyond the purelly superficial first order perspective, the more reasons pop-up not to have a fuel tank on a door.

The first concern would be "why are we designing things for ICE vehicles at all?" There's no reason to make general-purpose cars any more that aren't electric.

You're absolutely right!

Difference is, the wings don't have hinges, which means airplanes doesn't need flexible hoses that can fail and leak between the wings and engines. Another issue are impacts. Airplanes are required by law to keep from hundreds to thousands of meters apart, something that cars doesn't.

And it's not like placing the tank in the doors would save any space. My previous car had the fuel tank right under the rear seat for example, which saved space for the trunk and kept it safe from collisions.

True but the wings are still structural and have the engines on them. Considering how much fual a jet needs you would struggle to find another place to put it. For a car there isn't the same struggle to find a space and if it's a small car you can make a smaller tank and stop more.

Planes what??

LLM’s don’t know anything.

They have no capacity for thought or introspection. It receives an input and selects tokens that match an expected output. That’s it. Yes it has been fed the entirety of human knowledge to be able to do this. But that’s like a human memorizing the entire mandarin alphabet but never learning mandarin. An Al just makes a sentence that looks right, or generates an image that matches the tokens in a prompt. I could make a mandarin sentence with random symbols, and it might even say something. Doesn’t mean I speak mandarin.
