I'm pretty sure those massive A-pillars are to avoid roof collapse during a tip-over and not airbags. My previous smaller car had the same airbags my new one (new ones a longer but just as narrow) has and had about half the width of the pillars, the new one is also twice as heavy (still light by US standards).

- Retric 4y agoBatteries are really heavy as are high power ICE engines and drivetrain etc. The minimum weight for tires, suspension, exterior panels, frame, interior panels, seats etc isn’t that bad. But it gets worse the larger interior you want from simple scaling.
- bombcar 4y agoOld cars had very narrow a pillars and they survived rollover just fine - look at the thickness of an actual full on roll cage and it is much smaller than modern a-pillars. It’s mainly the airbags (and the angle of the windshield too I suspect) - and that it is simply not an aspect that is controlled for in testing to allow a vehicle to be road worthy. Add a tax based on degrees of width of A pillars and they would start shrinking.
