科普频道 Technology Connections 拿 LED 红绿灯因不发热而无法融雪遭投诉甚至被甩锅为车祸元凶的真实事件切入，生动揭露了新技术推进中常见的“万一偶发缺陷”反向辩驳逻辑。
为什么 HN 推它
被 HN 反复引用的经典案例，专门用来反思电动车、太阳能等技术更迭中常被极端边缘场景卡住脚步的认知谬误。
「我很喜欢 Technology Connections 对这类辩驳逻辑的剖析。」HN 网友原话：I love Technology Connections' take on this line of argument [0]
英文原摘要（HackerTube / Claude 整理）
Technology Connections explains how LED traffic lights, which do not melt snow, drew complaints and were blamed for accidents. He uses it to illustrate the 'but sometimes' fallacy against new technology.
Cited constantly as the name and example of the 'but sometimes' argument, where edge cases are used to resist better technology such as EVs and solar.
HN 上的提及

The one on traffic lights is way more interesting than it sounds! Everybody should check it out.
Technology Connections has a great video on LED traffic lights and how the concern about snow was overblown
I feel like Technology Connections did a better approach to the same topic of innovation
