Those bodies routinely enforce road widening and other measures in residential areas that make things grossly more dangerous. They also have explicit tradeoffs between the changes they make and deaths, proving the article's point. Plus the guidelines often prioritise speed as an end goal rather than caring about throughput, or the fact that it should be a quiet residential street. Plus the destruction of transit. Spending just as much as safe, accessible transport would cost on road widening projects and barely keeping deaths under a high self-declared threshold isn't prioritising safety.
