Early morning and I am driving to Sunriver for a meeting. It is a cloudy November morning. Suddenly I sensed what seemed to be a light flash in the corner of my eye. Naturally the first reaction is to look into the rear-view mirror, and yes there is a car behind me. Observing it for a while there are no further high beam flashes, so I turn my attention back to my own driving. Well, here it is again – I quickly look up and am again training my eyes on the car behind me for a moment – still no flashes. Now sensitized I started running through possible reasons a courteous driver would be trying to alert me – flat tire, open ski rack, a deer or another animal? But none of this was panning out after checking my surroundings and the built-in monitoring of the car. This is disconcerting – yet here it is again. As I turn my head to the side, I discover the culprit – there are narrow gaps in between the clouds and as I am driving I pass through short areas where sunbeams shooting through those gaps shine angled from behind into my side windows and reflect off the speedometer – creating the “in the corner of the eye” light flash that I mistakenly attributed to the car behind me. Puzzle solved and a boost in attitude – no problem with the car and a new outlook for a perhaps sunny day after all!
