Hate standing in line? Japan now has self-driving chairs

Standing in line for the latest iPhone at the Apple store, queueing for tickets to Wimbledon or even just waiting at the post office might just have got a lot easier. Japanese car-maker Nissan claims to have just the thing to relieve the sore legs of weary queuers. The new system of'self-driving' chairs is designed to detect when someone at the front of the queue is summoned, and automatically move everyone else one step forward in line. The chairs are equipped with autonomous technology that detects the seat ahead. When the person at the front of the queue is summoned, the empty chair at the front can sense it is empty, so moves out of pole position.
