The joke is with the transit system you can't even poke around inside the tram itself, they're being amazed by your character being completely static and switching to different positions with an animation sequence.
They're also four years too late to a system that actually lets you move around in the tram in real-time, and doesn't take any of the gameplay mechanics away from you... you can even get killed by it if you stand on the tracks:
