I think it's because it critically was missing context. So you're constantly trying to frame and reconcile it while reading. When first reading I thought there was actually a car brand named X -- and it doesn't seem out of the question.

But it makes the content seem awkward and clunky. So a reader going in with the correct context has a very different experience.

I didn't find this hard to read or understand, though perhaps his writing style just aligns with my own and I do have experience in the methods being used.

What a ludicrous complaint. It's perfectly readable. What possible motivation does one have to broadly proclaim something is "badly" done from an armchair without a modicum of justification? And then follow it up with an AI-whine. It's roiling to me.
