Many years ago mercedes trialled something along these lines. I was fortunate - if thats the correct choice of word - to sit in it at a show in frankfurt. I sat in it for about 30 seconds then climbed out and told the demonstrators that I never wanted to ever drive a truck with the drivers seat in the middla as this MAN seems to have. The reduction in visability when maneuvering is appalling, and no amount of additional mirrors and blind spot cameras can compensate. Added to that is the fact that every reversing maneuver is a 'blind side' reverse no matter which way you go and you have a recipe for an accident thats not too fussy about it's choice of where to happen.
The aerodynamics look interesting and I could quite easily envisage some of these being used by larger fleets as publicity showcases, but trucks lead a hard life. Fiberglass gets damaged, and rather than have a very expensive replacement or repair they are usually removed.
No, like all those exciting concept vehicles you see at motor shows, I think this will quietly slip away.
Some years ago the refuse trucks in this area were Dennis, they too had centre druver and a crew bench behind- they lasted about a year, and were replaced with RHD as per normal.
But the emphasis is this type situation is always it seems to me to be approached from the wrong direction.
You cant make a road vehicle idiot cyclist/pedestrian proof.
just plain common sense on the part of thw cyclist is all that is needed.
See a truck and keep clear.
