It's night and I'm driving into the gray cotton of fog caused by a lingering temperature inversion. Vision is limited, the roads are wet, it's just a few degrees above freezing and some of the traffic to my left is driving like it's a sunny afternoon in August. As they whoosh by me nose to tail at speeds exceeding the posted limit I marvel at what I imagine is their ability to see so much better than I can. I also admire their ability to anticipate and use quick reflexes to get themselves out of trouble if something unexpected happens ahead.
As of today, ICBC will probably have received reports of more than a quarter of a million collisions so far in 2017.
About 85% of the information that we need to drive comes through our eyes. Darkness and fog limit our ability to see which means we may suffer from a lack of data to make decisions from.
