Star Wars: Rise of the Resistance is considered the most complex theme park attraction ever built, and its frequent "downtime" in 2026 is due to the precarious interplay of four distinct ride systems. The attraction utilizes trackless ride vehicles that rely on complex sensors and Wi-Fi to navigate; if a single vehicle loses its "positional lock" by even an inch, the entire system enters an emergency stop (E-Stop). Furthermore, the ride features massive animatronics (like the A-1000 Kylo Ren), a motion-simulator "drop" section, and sophisticated projection mapping. If any of these systems fail to "handshake" with the others in the exact millisecond required, the ride computers shut down for safety. Additionally, the "pre-show" involving the shuttle transport is a separate ride in itself; if the doors fail to cycle correctly, the line grinds to a halt. Because it takes 30–60 minutes to "re-index" and reset all the trackless cars after a shutdown, even a minor sensor glitch can result in the ride being closed for a significant portion of the day, much to the frustration of guests who waited hours.
