Really? Because all I remember is "It would make you a better driver" because different vehicles handle differently. So? Why would actually driving a semi make me better at driving a car? I can understand how semis handle, how they need much further stopping distance, basic dynamics of a large truck without ever sitting behind the seat. I also know truck drivers have limited sight lines because ... wait for it ... I read about it and it's logical.
I didn't ignore them, I don't think it proves your point.
You don't think real world experience has any value and you think your own five minute consideration of 'what you imagine other perspectives to be' is all the insight anyone could ever gain from anything. This is an unusual perspective for someone posting on a discussion board to take. (Well, not that unusual, to be fair.)
Although, thank you for proving that @SableWyvern's position ('no-one is rejecting the potential value of other perspectives') to be incorrect.
