The first-of-its kind European experiment is a glimpse into the future – synchronised autonomous trucks stop and start in tandem, and drive closer together, so they can ease the congestion of busy motorways.

Because platoons drive in huddles, they also experience reduced air resistance, and can save upto 10pc of their fuel.

Later this year, similar 10-truck platoons will drive themselves on British motorways. In March, the Department for Transport confirmed that it is planning trials of HGV platoons, likely on a secluded stretch of the M6 in Cumbria. This is the future of urban transport.
