We observe the approach of a Passat estate, it stops, the driver gets out, slams the door shut and, as he walks away from the car, he aims a remote control back at it. That car now proceeds to reverse park itself into the available space, it then independently cuts the engine and activates the door locks. End of performance. In reality, there is nothing at all fantastical about this demonstration. The live performance by Volkswagen can be viewed at this year’s Hanover Fair (21 to 25 April)
