If my mind became the real world then you would find yourself in a strange place. It would be common to find slides for adults in my world. It would be a legitimate mode of transport, just like a lift. The slide would spiral around like a helter skelter or go towards an important location. Slides have two directions, forwards and downwards.
On a metro rail system, people can take a slide down to the platform, the slide would have rollers with magnets in them. As the rollers spin, the magnetic field would move through wires below and generate electricity to help the station with power slightly, it wouldn't be enough to power the lights in the train station but it would help a bit. To leave the station, pedestrians would walk up a twisting ramp with a very shallow slope so people wouldn't realize they are ascending several meters upwards by walking. Slides would be everywhere, shopping malls, government buildings, multi-story car parks. Some slides would just be a sheet of metal, others would be rollers. The slides would have a self cleaning system, the pedestrian's bum wipes the dust off the slide surface, simple and effective.
