Roborace's Self-Driving Car Takes On England's Swankiest Track

Once a year, the bucolic grounds of Goodwood House in West Sussex, England, are consumed by the smell of exhaust fumes, the sound of engines revving, and an excited crowd of 100,000 people, all wanting a look at the special cars on show. They gather here because Charles Gordon-Lennox, the 11th Duke of Richmond, likes to occasionally open his home to host the Goodwood Festival of Speed, a celebration of all the history, the heritage, and the future of motor racing. This week, among the supercars, hypercars, and pure racing cars, Goodwood visitors will spot a low, black machine streaking in near silence up the winding driveway to the estate, which for the event is transformed into a 1.16-mile hill climb track. "We're pretty sure when the car appears, people will freak out," says Rod Chong, deputy CEO of Roborace. And it will be the first machine to give the hill climb a try without a human in command, so there are some nerves.
