Ped on the left (Chap) reacts immediatley by looking in exactley the same direction as the female ped on the left...in reality he would take seconds to react like that. (this suggests they are both actors set to walk the frame and react)
Also, street is pretty much empty except for these two peds...no traffic, no peds...sunday morning shoot!
The bus reacts too violently, and would have to have been going much faster than a road like this would allow to swerve like that...buses generally never reach more than 30mph..so stopping in a straight line is possible, even in an emmergency
then, the bus is too clean and shiny (especially the roof), as well as being conveniently square and easy to model/render.
not a bad fake though
