Almost all roads are designed in the US by a professional engineer who is legally liable for the design. we need hold them responsible for not designing good infrastructure. If politicians don't allow for something safe than their job is to say it cannot be done.

If you are ignorant of things well known in the literature that is not a mistake. Even if everyone else is, that is not an excuse, their job is to design things safe.

I wonder about your life, if you can be so certain that people do not make mistakes. I really am curious how it would be to live in such a world.
