Imagine yourself sitting behind the wheel of your car. Then imagine that you count all the cars going in the opposite direction. One, two, three, four… but before counting the fifth car you should be aware that the driver with statistical probability has critically poor vision. This means that he or she poses a danger both to you and to others on the road. To shed some light on this fact we produced this film for the Swedish optician Synoptik and The National Vehicle Safety Inspection, ”Bilprovningen”.
