The research is in (it has been for decades now): our roads are designed to be dangerous because we focus on speed of cars, not balancing safety in our considerations:
It’s almost hard to read the whole book. Each section is only a few pages, but they just keep hitting you with data about how badly our traffic systems are designed. The mixture of bad policy, bad modeling, bad engineer training, and bad community perceptions about solutions makes it very hard to get change done quickly, but at this point all new roads and any rebuilds should follow drastically different approaches than we used 80 years ago. To do otherwise is just open negligence on the part of the road designers.
