Japan Post will reportedly start trialling self-driving delivery vehicles on public roads in Tokyo next week with the aim to set up a fleet by 2020 to cope with driver shortages. Prior to the trial, the company today held a ceremony at its headquarters in Tokyo and demonstrated a self-driving vehicle on a nearby public road, Kyodo News reported. Japan Post President Kunio Yokoyama highlighted at the ceremony the company’s "social responsibility" to offer delivery services in a sustainable manner. "The introduction of self-driving vehicles is a pressing agenda," he said.
