Harry Potter and the Forbidden Journey, located at Universal Parks, is not "fast" in the traditional sense of a high-speed roller coaster, but it is an extremely intense and complex motion-based attraction. The ride vehicle is actually a robotic KUKA arm mounted on a moving track, which provides a high degree of agility rather than linear speed. While the vehicles only travel at a modest pace through the physical sets, the arm can whip, tilt, and pivot you 360 degrees with significant force to simulate the feeling of flying on a broomstick. The most "intense" sensations come from the rapid transitions between physical animatronics and massive projection screens, which can make you feel as though you are plummeting or soaring through the air. Because the ride features sharp, swift movements and moments where you are tilted nearly onto your back, it is notorious for causing motion sickness, even though it never reaches high velocities or includes large gravity-defying drops. For many, the "speed" is perceived through the kinetic energy of the robotic arm rather than the miles per hour of the vehicle.
