I drove one of the last Orion I that Waukesha Metro had before they were retired. I aways said that I would not want to get my arm caught in the door. I would think it would take it off, way the door would slam shut. It was a good bus to drive but you had to take the turns wide. It did not have A/C, so I did not like to drive them on hot days.
Too bad they did not have more shots of the bus.
