What's he doing? Cabby leaves door open as he inches forward in heavy traffic

A driver was travelling along what appears to be Airport Boulevard when he spotted a taxi driver inching through heavy traffic with his door wide open.

In a video posted on the Singapore Taxi Driver Facebook page yesterday night (Apr 16) by Chu Teck Fah, the blue Comfort taxi can be seen driving along the road with the door open throughout the minute-long video. 

Netizens who saw the video were amused, with one giving a very blunt comment: "He farted."

Another gave a possible reason as to why the incident might have happened.

"He is sharing his music with others in the queue.

"By opening the door, the speaker on the door can spread the sound better."
