Road safety works best when design forces the right behavior, not when sign begs for it. Road safety works best when design forces the right behavior, not when sign begs for it. Don Norman, in The Design of Everyday Things, calls these forcing functions: design elements that make the wrong behavior difficult or impossible. Instead of relying on perfect attention, they guide behavior by default. This approach is standard in software, web, and product design. When the stakes are high, we design systems that anticipate mistakes. Streets should be treated the same way. Safer roads come from design that makes safety unavoidable, not signs that hope people comply. #uxui #carculture #donnorman #design
