If you are talking about an urban boulevard, then I agree. Engineer the street to lower speeds, and increase safety because there are pragmatic options (roundabouts, speed bumps, more signals and stop signs. But if you are talking about intercity highways, something like Los Angeles to Phoenix to Denver to Des Moines, then just increase the speed limit.
