This YouTube clip is about as uninteresting as the inside of a door knob …… until you get about 75% of the way through it. It then shows some of the features of a US megabus including video screens and, very surprisingly, the seats appear to be able to be turned around! Maybe it’s a feature of the seats the guy appeared to be sitting in (front pair) and is not for the use shown? Something to do with wheelchair access? Anyway, with the flick of a lever the guy can swing the seat around.
