You've heard of unruly passengers fighting at the airport before. But what about a showdown between AI robot wheelchairs? 

Local comedian Rishi Budhrani recently shared a hilarious clip showing what can only be described as an awkward face-off between two AI robotic wheelchairs at Changi Airport Terminal 3 on April 14.

The incident involved two of the airport's self-driving mobility devices that came to a complete halt when they met head-on along the terminal's walkways.
