Personally I'd feel very unsafe passing, or being passed, by this particular setup. There is no way that conglomeration of vehicles could be controlled in any kind of panic situation or panic stop. That, to my mind, is what makes it unsafe. A guy pulling one trailer behind his 5th wheel may be illegal, but not necessarily unsafe. This combination of vehicles was unsafe and should have been pulled over. Control in anything other than straight and steady would be impossible.
OTOH people doing 10 mph over the limit in a controlled manner are not inherently unsafe. Contrary to popular postings, speed doesn't kill, unsafe drivers kill, whether they are speeding and driving erratically, or driving an obvious unsafe combination of vehicles.
