The "A-pillar" is the vertical frame of a car windscreen. With modern "safety" design, its been getting bigger and bigger. Im sure my one crash with a car was because I dissapeared from view behind the pillar.
Now Volvo are designing an A-pillar which has glasss see-through sections, so cyclists and pedestrians can no-longer be hidden from view.
Im glad to see one manufacturere recognise this fault.
