You are discussing - ranting about, really - what should be.
The rest of us are discussing what is.
The original claim is that people aren't buying the F-150 Lightning because (paraphrasing) people want mid-size trucks and not fill-size trucks. That claim is refuted by pointing out that mid-size trucks already exist, they do not sell very well, and in fact full-size trucks are overwhelmingly popular.
Now you come in with your righteous indignation that because, in your view, people don't actually make full use of full-size trucks, they should not be buying full-size trucks. Notwithstanding that the majority of these trucks actually ARE used as trucks - because the cultural bubble that exists entirely up your ass along with your head is not representative of the entire world - the very real popularity of these vehicles is not dependent on what people actually do with them.
I'll say it again just to be crystal clear: It does not matter if you think they should not be popular, the fact is they are popular. Reality does not give a shit what your opinion is.
