“Where would you like to go?” Siri asked. It was a sunny, slightly dreamy morning in the heart of Silicon Valley, and I was sitting in the passenger seat of what seemed like a perfectly ordinary new car. There was something strangely Apple-like about it, though. There was no mistaking the apps arranged across the console screen, nor the deadpan voice of Apple’s virtual assistant, who, as backseat drivers go, was pretty helpful. Summoned via a button on the steering wheel and asked to find sushi nearby, Siri read off the names of a few restaurants in the area, waited for me to pick one, and then showed the way on a map that appeared on the screen.
