It was bound to happen: an autonomously driven vehicle has crossed the U.S.

Automotive supplier Delphi Automotive PLC said it has completed the longest automated drive in North America, traveling from San Francisco to New York in the first coast-to-coast trip ever taken by an automated vehicle.

Nearly 3,400 miles were covered and 99 percent of the drive was done in fully automated mode.

The nine-day trip crossed 15 states and the District of Columbia. Along the way, the vehicle encountered various driving situations such as traffic circles, construction zones, bridges, tunnels, aggressive drivers and a variety of weather conditions.

The company explained the drive was used by Delphi engineers to research and collect information that will help further advance active safety technology, which is the most rapidly growing technology sector of the auto industry. The team said it collected nearly three terabytes of data.

“Our vehicle performed remarkably well during this drive, exceeding our expectations,” said Jeff Owens, Delphi chief technology officer. “The knowledge obtained from this trip will help optimize our existing active safety products and accelerate our future product development, which will allow us to deliver unsurpassed automotive grade technologies to our customers.”

Delphi’s automated driving vehicle used for this drive is a modified Audi CUV equipped with a full suite of advanced technologies and features, many of which are already on the market today including collision mitigation, integrated radar and camera systems, forward collision and lane departure warning.
