The conditions that are necessary for this thing to work will be numerous and highly restrictive. People have already mentioned “no tall vehicles”, “no roof mounted bicycles”, and “no curved roads”. Those are significant, but not prohibitive. Especially in China, where it seems reasonable to assume that they can enforce restrictions that would activate armies of lawyers in the USA.
I can think of several more restrictions offhand. Some of them were discussed in the responses to Corey’s previous thread. No bridges on route, below a certain height. No overhanging wires (same). Traffic signals moved out of train path. And above all, some way to keep drivers from EVER stopping and opening a vehicle door when the big bad train is coming through!
