I did relocate the rear view mirror higher up on the glass to rid myself of that blind spot , but they are talking about the A pillar.
Even in my Rally racer, we were able to fabricate the A pillar bars so that there was no loss of visibility around the A pillars.
The photo they show in the article looks like form a Lumina APV. My dad has one of those and I hate driving it due to the huge blind spot due to its massive A pillars and strangely sloped windshield.
Anyway, I don't get it. I don't have a problem with my Jeep Cherokee blind spots.
