It is all because of the Chinese Construction Industry.
Hah! Called to mind my journey to the university the other day ... construction site on one of the main roads running down through town ... four-vehicle-width carriage-way, with a "frog-lane" on either side — i.e. bus lane separated from the main carriage-way by islands planted with mango trees; also treated by light traffic as a reverse direction route so as not to bother to cross the main carriage-way! — heavy-ish traffic at the time. The frog-lane was blocked by 8 huge cement carriers ... waiting their turn at the single pumping machine to have their cement pumped into whatever caisson-structure with reinforcing steel rods had been prepared for it. The JIT side had somehow not worked that well ... the impediment to traffic-flow probably lasted a good couple of hours.
Still that's better than 140 streets in the centre of Beijing being totally grid-locked for 5 hours as a result of a wee downpour JIT'd for the beginning of the evening rush-hour!
