Guessing where cars are heading has preoccupied generations. Every motor show I remember had concept cars. Some of General Motors’ predictions from the 1938 Buick Y-Job to the 1951 Le Sabre were more than flights of fancy. HG Wells predicted aircraft, tanks and texting yet he was hazy about cars. He imagined motorways like railways connecting cities, decanting people on to bicycles in town. Some 30 years ago Prometheus sent me driverless on test tracks to show that ingredients for autonomous controls were already here. Now the Royal College of Art’s Intelligent Mobility Design Centre and the Helen Hamlyn Centre for Design is presenting Driverless Futures, Utopia or Dystopia? At the London Transport Museum
