most engineers actually doing the road design 'assume' drivers are mostly rational actors and are not overtly defensive in their design. Instead, they wait until crash data collected after the fact forces the issue.
This is absolutely wild to me. I'm an engineer, mechanical background, related to traffic in the air rather than on roads, and we have SO MANY REMINDERS pushing the idea of proactive safety measures and mistake-proofing any potential safety hazards. From industry standards to regulatory body and customer requirements, to internal procedures, backed by tools and specific courses in engineering coursework. Folks would be in jail if they acted like this, like, "yeah, that plane door might fly open if some idiot goes at it the wrong way but *shrug, we'll tweak the design once someone actually does it and kills a planeload of people.
I hope it isn't hashed ๐๐
