Hmm, it seems not to always show the actual route that buses take though. Just looking at one route and seeing the red dot indicating a moving bus apparently go through two culs-de-sac and a footpath (yes, the most direct route between two consecutive bus stops on the route - if you go on foot), rather than on the actual through road the buses use...
Indeed - I've seen this, or something like this on three different routes now. The other two cases involving a hail-and-ride section (and the red moving bus shown as taking another, parallel road); and a one-way system, with a red moving bus shown as taking the wrong way around (a fairly extensive) one-way system, on which the bus stops in each direction (on different roads) possibly share common names (taken from the roads that link each side of the one-way system).
So, a good thing, but some fine tuning needed!
