Truck of the future?

I think we've been here before.

Where? Back to the future?
It'll come soon enough - always does.

I have yet to se a decent image of the MAN wagon, I'll let you know my feelings then. (I'll re read the article when I get home, the screen setings are better there.)

I can think of better ways to protect cyclists! Train THEM better and, enforce it. Too many (not all, by any means) vehicle vs cycle accidents are (partially) the fault of the cyclist, putting themselves in harm's way.
Too many "civilians" don't respect their own safety, on the roads. Especially around larger vehicles, of all types.

Not very good if the "mirror arms" are not retractable.

Trailer has the same volume as a standard trailer but I wonder how useful that volume would be. I am presuming that many loads are square/rectangular (either stacked on pallets/trolleys) which would tend to lead to wasted space on a trailer which isn't 'box' shaped.
