A person riding a bicycle has unobstructed views. They see far more than someone sitting in a car.
The A-pillars are a great example of trade-offs. Their intended function is structural integrity -- keep the roof and windshield where they belong in the event of a crash. But A-pillars create significant blind spots for the driver. SUVs and pick-up trucks (America's favorite vehicles) have super wide A-pillars.
When a car turns, particularly at intersections or in parking lots, the A-pillar can obstruct the view of pedestrians, cyclists, or other vehicles. Probably the most dangerous scenario is when a driver is turning left while someone is properly using a crosswalk. The driver is focused on beating oncoming traffic and cuts the left-turn at an angle.
Drivers have to compensate by moving their head or taking extra caution, i.e. slowing down. Decades of crash reports reveal that drivers don't like moving their head or taking extra caution.
Back to the reply guy below. It's super important for people driving a motor vehicle to come to a complete stop at a stop sign, move their body to see around the A-pillar, and drive cautiously. Those of us sitting on a bicycle are doing our best to avoid you because we know it's a struggle for you to exercise extra caution while operating powerful motor vehicles.
