What is happening here? Did the engineers forget that they were supposed to optimize for safety, and instead optimized for getting people to slow down? Does the net effect of this improve safety, or worsen it?
If everyone drives as fast as they can while meeting some perceived safety level, then does that mean these efforts are unlikely to affect safety and merely to slow everyone down? Is the best set of measures the maximally deceptive set, which looks as dangerous as possible while being as safe as possible?

No. It means that people are usually wrong when they judge the safety level of their driving speed on a nice clear road that happens to have pedestrians next to it or trying to cross it, but are more accurate at judging safety when they are primed to expect obstacles, steering challenges, other actors moving not in parallel with them on the road itself. https://www.ite.org/technical-resources/traffic-calming/ https://www.ite.org/technical-resources/traffic-calming/
