Self-parking was just one of several autonomous exercises, including overtaking, reading traffic lights, avoiding a pedestrian darting into the road, that the Leaf prototype demonstrated.
I suspect I am not alone in feeling uneasy about letting a computer drive me to work or the shops. But every time I get stuck in stop-and-go traffic and think about how I could be focusing on other tasks, the concept of the autonomous car becomes more and more attractive.
