1. riders must not read signage in a given language or alphabet

it's literally in a specific alphabet. If you were an Arabic speaker these letters would be just as much gibberish to you as Arabic letters would be to an English speaker. Not just gibberish, but hard to tell apart.

2. very quick to see where you need to be and which bus you should board

I watched the video to just to be sure i wasn't missing something but... no. So very much _no_. I assume that to _you_ this is clear. To me this is modern art. I think if you explained it to 10 non-geeks you'd get... 10 people saying "no, this is not fast or easy" maybe with sufficient training, but even if you got 100% adoption amongst locals any foreigner passing through would be absolutely screwed.
