Driverless Cargo Trams to Debut at Haneda Airport in Tokyo
From The Japan Times:
It can pull up to six containers at a time, trundling between aircraft and airport buildings over a distance of around 2 kilometers with no driver in the cab.
The Level 4 vehicle, meaning that it does not require human interaction in certain settings — although a human driver can still request control — has been in operation since July 1.
