Thicker windshield pillars create visibility hazards despite improving rollover safety, reporting says
Modern vehicles feature wider pillars due to federal safety mandates and internal hardware, according to Jalopnik.
The short version
- Modern vehicle A-pillars have expanded significantly to meet rollover roof-strength regulations and house components like airbags and wiring.[Jalopnik]
- The larger pillars improve occupant crash protection but create substantial blind spots that can obscure pedestrians and cyclists during turns.[Jalopnik]
- Automated detection systems are present in some vehicles to assist drivers, though their reliability remains variable.[Jalopnik]
Key facts
- NHTSA established roof-strength rules phased in between 2012 and 2017 requiring roofs to hold three times the vehicle weight.[Jalopnik]
- The IIHS introduced a stricter roof-strength evaluation in 2009 and discontinued it in 2022 after most vehicles achieved top ratings.[Jalopnik]
- A-pillars house structural reinforcements, airbags, wiring, speakers, grab handles, and head-impact padding.[Jalopnik]
- Wider windshield pillars can hide pedestrians and cyclists, especially when vehicles make left turns.[Jalopnik]
What remains uncertain
- Pedestrian and blind-spot detection technologies built into modern cars may not perform reliably across all driving conditions.[Jalopnik]
