In the scene where the bus is getting off the interstate due to heavy traffic, you can see at least 3 shots where cameras have been mounted to the bus. The 1st camera can be scene in the shot just prior to when the bus hits the water barrels. The camera is small and is mounted just below the bus' left bumper while in the very next shot the camera is clearly not there. The 2nd camera is mounted on the left side of the bus (our right) and can be seen in 2 different shots. 1st, is when the bus starts hitting the arrow signs. The 2nd time is when the bus is going thru the red light. This is the best shot to see the camera.
