There are no near misses on Dueling Dragons (formerly at Universal's Islands of Adventure, now replaced by Hagrid's Magical Creatures Motorbike Adventure).
The ride was a **dueling inverted coaster** with two intertwined tracks (Fire and Ice). While the trains appeared to race toward each other in near-head-on collisions, **precise engineering and block zone systems ensured they never occupied the same space simultaneously**. The "near miss" was a carefully calculated visual illusion—the trains passed at safe, predetermined distances (several meters apart) at high speed. The sensation of a close call was entirely intentional design, not an actual safety hazard. The ride operated for 18 years (1999–2017) without a single collision incident.
