Design a Roller Coaster Simulator

Design a system for a roller coaster simulator video game where players build coasters that are scored and ranked on an online leaderboard. The system must support multiple coaster types, each with distinct scoring functions composed of a type-specific Comfort Score and an Overall Score (ScaleFactor * ComfortScore * MaxSpeed). Your design should be extensible to 10–20 coaster types and process many submissions efficiently.
