I believe that semi trailers have been converted to passenger use in Cuba at various times.

IMO, if the US were to be hit by a severe economic decline, converting semi trailers to passenger vehicles could be done quickly, and, cheaply, particularly safety standards were ignored "wink, wink,"
In the example shown, assuming a sit-down configuration 4 abreast (remembers times are tough), about 48 people could sit on the bus. Sidewise seating and standing riders, perhaps 72.
Theoretically, again assuming a "wink wink" attitude towards this mode, truck trains might be built

The conversion would have lower passenger carrying capabilities per unit than shown in the Cuban example, say 36 and 54, but, the 4 unit truck train shown might carry between 144 and 216 people.
Oh yes, with computerized braking systems, this might even be a bit safe on snow. Add small motors to selectively power 2 of each trailer wheel set, and it might even be safe.
I would expect the PMPG for a 4 (or more) unit passenger truck train to be right between a plug in car and a freight train per person.
A last thought: moving company trailers might even be doubled decked!
