Here, SVT's reporter rides in the self-driving truck - on the E4

With the help of a large number of cameras, sensors and advanced calculations, the truck can drive without a driver.

Since Scania's self-driving trucks are still in the research stage, a safety driver needs to be ready at the wheel if something goes wrong, and a technical engineer sitting next to him and monitoring the computers.

- I can press the emergency stop, then you disconnect the entire robot system and then the driver drives, says Göran Fjällid who is a technical engineer at Scania.
