Visor-less trucks.What's up w/that?

I am referencing the freightliner cascadia that many companies are going to.I assume that going visor-less must have something to do w/fuel mileage and fuel mileage IS the new rage. I have been cognizant of the visor-less truck after having driven one way back when.Ya it was a cabin over and I merely pulled both shades down and to this day,i ride w/both shades down and i have not been in a visor-less truck in over a decade and have not been in a cabover in longer than that.
OK.PRIME's newest and quite flashy actually truck is the cascadia.One can not help but notice them as they are clean,bright and shiney.Guess what else? They are visor-less.
Do any of you notice the same kind of stuff that I tend to or am I that far off w/my likes and/or dislikes as i soak in,visually,the new trend in trucks? Could this visor-less spec'ed truck be a victim of costs and these companies are SO cost concious that they order a fleet w/o the basic necessity of an external visor?
I am beginning to not enjoy the change that we as drivers are experiencing.That may need to be posted in the political section.sorry-

 

I get the truck paper every week w/o fail and i have indeed seen them.My post was about the companies not putting them on the ordered fleet trucks and wondered if it had to do w/cost or w/fuel mileage,or maybe a combination. I think it is hideous to not put a visor on a truck.
i appreciate your reply though.
