I know most comments indicate that even without the maths, the rolling geography would seem to block the view, and that the best solution would be a 4-way stop, a roundabout or the split road suggestion in the article.
But going back to the a-pillar, Volvo did have a concept design with a see through a-pillar. I'm not sure why it never made it to market. I'm guessing it didn't pass their safety requirements?

- azernik 9y agoJudging from the considerations evinced in this article, pillar strength and thus rollover safety do seem to be limiting factors: https://www.redbook.com.au/car-news/toyota/toyota-patents-transparent-pillars-invention-108558?csn_tnet=true https://www.redbook.com.au/car-news/toyota/toyota-patents-tr... It also indicates, however, that the industry is putting real development effort into solving the problem, whether through clever optics like Toyota's efforts, or cameras and screens like Jaguar's concept.
- anonymfus 9y agoMay be it would be possible to improve rollover safety by putting additional pillars inside the car, for example between chair backs?
- caf 9y agoI would have thought you could build an open truss pillar that was as strong as a solid one.
- ScottBurson 9y agoSeems like a negative Fresnel lens in the lower corner of the windshield would suffice. I've had trouble with the A-pillar in my 2015 Prius; I may try this.
- toomanybeersies 9y agoA 4 way stop is unnecessary, simply requiring one direction to stop would work fine. In New Zealand, with rural grid roads, they usually have 2 way stops (or give-way/yields) which will alternate, so you get priority at one intersection, then stop/give way at the next, and so on.
- djsumdog 9y agoThe article mentions a yield sign, right? I don't think that's enough. There needs to at least be a stop sign. Given the severity of the accidents, I don't think it's unreasonable to just go all out, especially if it really is a rural road with minimal traffic.
- toomanybeersies 9y agoYou're right. It's been a while since I've driven in the countryside, but I do remember a few of the intersections where visibility isn't so great due to trees etc. having stop signs. Obviously, human error is a problem too, as the article states. You should't be driving at 37 mph though an intersection with a yield sign in any case, which I guess is the whole point of the article and the suggestion to turn the intersection into two T-intersections.
