Here’s the reality: cars that drive themselves are already arriving to market, one button at a time. We have cars that swerve to avoid accidents or park themselves. Cars like these are already wreaking havoc. Maybe one of the funniest viral examples you can find on Youtube is of a bunch of people at a car dealership, testing out a feature on a Volvo that they think prevents it from hitting pedestrians. You can’t see the hapless driver settling in behind the wheel, but let’s imagine him wide-eyed, bristling with excitement as he prepares to slam on the accelerator. In the foreground stands a guy in a pink shirt, his posture giving off this brittle mix of apprehension and excitement. He’s leaning forward, bracing just a little bit: Ready for magic. Holy shit!The driver slams on the accelerator. The car doesn’t stop. It plows right through the guy in the pink shirt, who flips up onto to the hood like a rag doll tossed by a pit bull. People scream. The camera spins wildly, forgotten.
