Wards has a fascinating piece on the recent evolution of the A-pillar, starting with the aesthetic novelty of the B5 Passat and ending with the various roof crush and head-impact safety standards that are creating ever-larger and more vision-obstructing pillars. But is the added passive safety worth the trade-off in visibility, and therefore active safety? A researcher equivocates:
We lack quantitative models that express the safety cost of vision obstructions. We’ve worked on it, but it’s difficult to see the relationships in crash data. People are highly adaptive, and any vision effects are buried in other larger effects due to exposure and driving style.
Inspired by the write-up, I found that the Royal Automobile Club of Victoria (Australia) has its own annual forward visibility rating system, and that it refused to give a single 2011 model-year vehicle a five-star rating (in a rare display of respect for the five-star system). Without a rating system of our own, I thought TTAC should embrace the subjectivity of the subject matter and pool its collective wisdom to help the automakers understand which vehicles need an A-pillar diet. Which vehicles feel the least safe in terms of forward visibility? Which need window inserts and which need to just slim down? Or have we reached the point where we need A-pillar cameras?
