You are cycling down a road. You are approaching several parked cars. In one of the cars is a driver talking on a cell phone who is about to hang-up the phone and pull out quickly. The car's engine is running, but quietly, and the wind in your ears hides the sound of the quiet motor. The high-backed driver's seat hides the driver pretty well. One or more of the windows of the car with the driver on the cell phone is darkened because the driver thinks it looks cool or wants protection from the summer sun. Consequently, the cyclist can't see inside the car too well. The sun this day is bright and somewhat making it difficult for you, the cyclist, to see. How can you be certain of spotting the danger of the driver about to pull out rapidly as you approach on your bike?
