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.
