The trucks could park in the dedicated loading bay which is just steps away, out of frame in the bottom right of the video (just past the tree). The WheelTrans bus can actively engage in loading/unloading here but can’t wait for a passenger, as they’re doing. There is a dedicated accessible loading zone just out of frame on the left, where the tour bus came from, that WheelTrans could use. All of these road users (including the cyclist) are being actively hostile and selfish to other users.
