Watch | Here’s why a fleet of trucks drove themselves across Europe

About a dozen trucks just drove themselves across Europe in a self-driving vehicle experiment by Scania and other truck manufacturers.

The technique is known as platooning and has been proven to save time and fuel, and cut down on emissions, as the trucks utilise the road better. The technique involved trucks communicating via radar, GPS, and Wi-Fi with the lead truck controlling the pace and route. And, as the video shows, if the lead truck is forced to make an evasive manoeuvre, the others follow close behind. In this instance, all the trucks had human drivers behind the wheel just in case they needed to take control and the whole experiment was closely monitored. But it does give us a glimpse at what may be the future of road haulage.
