An anonymous reader writes We've heard about all the effort going into self-driving cars, but what about the massive fleet of trucks we use to deliver goods around the country? Well, Mercedes is trying to tackle that problem. They have just demonstrated an autonomous 18-wheeler on the German Autobahn. It's clearly a long-term project; they named it "Future Truck 2025," as an unsubtle reminder that this tech needs a lot of development before it's ready for common use. "Special cameras and multiple radar systems watch the road, the sides of the road, and cars and trucks behind the vehicle. Future Truck is also envisioned to communicate with other vehicles and connect to growing sources of online information as Big Data balloons on the road. ... Many of the component parts to put a vehicle like this into production are already available in trucks on the market: Systems that help drivers keep their distance from other drivers, active braking assistance, guidance and mapping systems, and fine-tuned cruise control and tons of other hi-tech tchotchke."
