Have you ever been driving and arrived at your destination not being able to remember anything about the journey? I have and it happened to me again recently. I wondered whether I had obeyed all the road rules. Had I stopped at stop signs and for pedestrians waiting at crossings? Was I courteous to other road users who were around me? I didn’t know. Not being sure whether I should be concerned, I set about digging into just how safe we are when we are on ‘auto-pilot’ and not consciously aware of what we are doing.
