中文导读
知名城市规划频道 Not Just Bikes 深度剖析北美限速规则的荒谬之处。他指出立块限速牌远不如街道设计管用：司机会潜意识顺应路况物理环境开快车，安全车速必须靠街道本身的设计来约束。
为什么 HN 推它
HN 交通安全与城市规划板块反复提及的开眼之作，彻底颠覆了很多人对「交规约束 vs 物理设计诱导」的传统认知。
「它真正让我看清了表面规则与实际行为之间的脱节。」HN 网友原话：it really opened my eyes on the relationship between rules and actual behavior.
英文原摘要（HackerTube / Claude 整理）
Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.
Recommended again and again in traffic-safety threads as an eye-opener on road design versus posted limits and driver behavior.
