We can also prevent people from driving 50MPH through residential neighborhoods with good street design. Current safety standards with open roads encourage people to ignore the speed limit. Safety features like raised crosswalks, curb bulb-outs at intersections, and roundabouts at small intersections like those used in Seattle all make it uncomfortable to drive fast. This would go far in reducing egregious speeding without the claims of authoritarianism that would certainly come with technological speed controls.
