Yes, Dick used to have his own ride! The Nightwing Ride opened in 2000 at Six Flag's New England. Riders lay in gondalas on their stomaches and were whizzed around giving them a sense of how Dick must have felt as he glided around the city.
Sadly, frequent breakdowns and expensive repairs prevented the ride from operating consistently and it was removed in 2008. From reports read online, it was a very popular ride.
