I think you're assuming their roads were straight. This wouldn't work at all on a winding road/trail where turns are constant.

  It would be a massive annoyance, but would still work better than a differential gear made with the materials science of the time. I personally think that the story is fantasy.

    There's nothing particularly difficult or expensive about a wooden differential. edit: no seriously, zoom in on this pic here https://upload.wikimedia.org/wikipedia/commons/d/d6/South-pointing_chariot%2C_China_Court%2C_Ibn_Battuta_Mall%2C_Dubai.jpg https://upload.wikimedia.org/wikipedia/commons/d/d6/South-po...

    At some point, a massive annoyance asymptotically approaches physical impossibility.
