Will we ever be able to trust driverless cars?

When you're sitting in the driver's seat at 60mph on a rain-lashed motorway, covering your eyes would normally be a dangerous, if not downright suicidal move. Putting on a virtual reality headset, obscuring the view of the road altogether, might seem even crazier. But that's exactly what I did recently. To start with, I was looking at a computer simulation of the motorway in front of me. Then the road disappeared altogether, the car took off, and I began flying through an alien landscape.
