Question

why are the mirrors fitted on the outside of cars are convex mirrors?

Answer 1

Over the past ten years or so, vehicle manufacturers have progressively introduced convex rear view mirrors on the outside of new cars. The argument presented for the convex mirror is that it provides a wide angle of vision and therefore less likelihood of not seeing a vehicle in the so called blind spot between a driver’s peripheral vision and the view rearward from the internal rear view mirror. This solitary and erroneous reason for their existence is considerably outweighed by a myriad of more potentially dangerous issues.
