Artic lorries don't have the driven wheels on the trailer ,the tractor
unit pulls it. most artic jacknifes occur under braking.
with the bendie buses the traction is at the back so on a slippery
surface the effect is like trying to push a length of string. its very
likely to bend.

At the risk of being boring, bendies have managed perfectly well in Europe
for 40 or 50 years; why is it that they don't have all these problems, if
they are are 'design weaknesses'?

Seems a little odd to me.
