The problems are lack of mirror coverage of their near sides made worse by

The high driving positions are due to the large engine that has to be
accomodated at the front. You can't put the cab in front of it because
of length restrictions , or rather you could, but then the trailer
would have to be shorter reducing the max load. As for under run
protection - remember that these things have to go over hump backed
bridges and other things where if they had fairings going down to the
ground there would be a high risk of grounding.
