If you want to fix the model to the view you can set it's
reference frame to viz.RF_VIEW. If you want the model to come into view only after the transport movement is started you could create vizconnect events for both left and right turns. Map the same input signals used with the transport for the events. Then in your script create callback functions for the events. In those functions, set the model's position so it comes into view or change its reference frame.
