By Alexa Delbosc It is humans, after all, whose errors contribute to 75% of road crashes, who introduce undesirable randomness into the mathematical simplicity of traffic flows, and who have been characterised (somewhat tongue in cheek) as “monkey drivers” with slow reaction times and short attention spans. If only we could eliminate the human factor, we would have cities teeming with safe, efficient cars whizzing us to our destinations. Right? Wrong. For better or worse, as long as there are humans in the transport system we cannot ignore the human factor. To do so grossly overestimates the promised benefits of driverless cars and underestimates the negative impacts they will have on our traffic networks and society.
