You can identify this as a standard "Butterfly" model because it has three supports under each hill. The "XL" versions have four supports under each hill. These little coasters can be installed indoors or outdoors. The manufacturer has built copies with a variety of themes, so some have much more complex cars than this one. This yellow car is by far the most popular design and color used on these little rides.
I often joke that lawyers in the United States would not allow a self-operated ride like this one, but there may be a bit of truth to that. To the best of my knowledge, there has never been a self-operated "Butterfly" or "Nordic Jet" ride in the United States.
