When will it become accepted practice that containers navigate autonomously from the sea to their final destination and back?
In 2019, the containerized shipping industry will have transported over 800mn TEU, generating earnings in excess of US$25Bn. These containers arrive in ports on container ships, where they face an immediate bottleneck as they are unloaded.
Self-propelled autonomous containers can be released from larger container vessels at sea and navigate to the customer by driving up beaches and entering into the road infrastructure. Later, they can make their way back to be picked up by container ships on the sea. 
Advancements in ubiquitous weather data, autonomous navigation at sea, advancements in container design, and safety protocols, are still needed to unlock this opportunity.[3,2]
