On the morning of April 8, a fleet of self-driving trucks arrived at the Maasvlakte port in Rotterdam, the Netherlands, completing the journey of the convoy across Europe. As we have reported in previous reports, this is actually to look forward to the future of self-driving truck fleets in Europe, as part of the European Truck Platooning Challenge trial, which has condensed the energies of six different manufacturers. 
The driver of the lead vehicle sets the speed and path, and other trucks automatically follow-up—these vehicles are synchronized via WiFi connection for both braking and acceleration.
In fact, this is not a completely automated system, but it is an important step towards automation. With this type of teaming, congestion can be reduced and the chance of accidents reduced, and fuel savings can be achieved. A white paper from Dutch research firm TNO mentions that every truck in the team, whether it is the leader or the follower, can save an average of 10% on each trip. The report also mentions that 90% of traffic accidents are caused by human error. Although a complete analysis report on the safety of this self-driving fleet has not yet come out, it is generally believed that this technology can make The accident happened even less.
In the recently completed challenge, the trucks were from Daimler, Volvo and Scania, and each truck team started from different locations. Among them, the Scania team has the longest journey, more than 2000km, which spans Sweden, Denmark and Germany and finally arrives in the Netherlands. However, these trucks do not travel in the form of a team all the time. They only do so on highways where traffic conditions are "normal." In fact, even the following vehicles are equipped with drivers.
The team challenge does demonstrate the viability of this technology, but European companies and governments need to develop detailed regulations. Cross-border regulations for self-driving trucks need to be introduced, and of course, the corresponding provisions of the team. For example, whether or not the team can be temporarily teamed up while driving, or the team must be planned from beginning to end; there are drivers like the car can not rest.
On April 14th, more content will be discussed at an informal meeting initiated by the European Union’s transport authorities. U.S. businesses and governments are also working on similar plans
