There is a FRIENDS amusement park set that has a roller coaster in it. It was originally selling for $100, but more recently came down to about $80 and has stayed there for months. https://www.bricklink.com/v2/catalog/catalogitem.page?id=145123#T=S&O={}
I sometimes see them in TARGET?.
I guess the appeal of this new set is that the ramp is steeper.
