So
No I just actually know what I am writing about.
Your ‘experience’ here means nothing to why and how equipment is designed.
You should be careful about what you assume about other people.
Well, what now, I thought it was all tailored to the user? Is there an engineer sitting in his ivory tower crying because it doesn’t work as intended?
I also know engineers from the armaments industry and had a tiny insight into design criteria, e.g. for the GTK Boxer.
But let’s leave it at that, we won’t be able to convince each other.
