When you’re driving at speed, being alert to the traffic around you will save your life. When a truck in front brakes sharply you have milliseconds to respond, but what if you’re seeing the past? Can your brain process the information it’s receiving quickly enough to avoid catastrophe? Or does it do something completely different and take a leap of faith to predict reality?

Professor Hinze Hogendoorn tells Anna Machin how real-time perception is an illusion and how our brains compensate for living in the past.
