终于有实锤了：缺少实体按键的车就是更危险

Core Viewpoint - The article discusses the ongoing debate regarding the necessity of physical buttons in vehicles, especially as car manufacturers increasingly integrate functions into touchscreens. It highlights a recent study that quantifies the impact of touchscreen operation on driving safety, suggesting that physical buttons may enhance safety and user experience in vehicles [5][9]. Group 1: Research Findings - A study by a team from the University of Washington demonstrated that operating touchscreen interfaces while driving significantly increases distraction, with interaction times nearly doubling from 564ms to 1140ms [23]. - The average lane deviation increased by 12.6% when drivers were distracted by touchscreen operations, indicating a substantial impact on driving safety [25]. - The study found that drivers tend to engage in "blind operation" of touchscreens, with 62.9% of interactions occurring without visual attention, which increased to 71.9% under higher cognitive load conditions [28]. Group 2: Industry Response - Some automotive manufacturers, including Xiaomi and Volkswagen, are beginning to reintroduce physical buttons in response to safety concerns and consumer preferences [41][43]. - The European New Car Assessment Programme (E-NCAP) plans to incorporate physical controls into safety ratings starting in 2026, indicating a shift towards valuing tactile feedback in vehicle design [44]. - Regulatory changes in China are also expected to mandate physical controls for critical functions, reflecting a broader trend towards prioritizing user safety and interaction quality in automotive design [45]. Group 3: Design Implications - The article suggests that the reintroduction of physical buttons could allow for greater design differentiation among electric vehicles, moving away from the uniform "tablet-like" interiors currently prevalent in the market [47]. - The tactile feedback from physical buttons is seen as a crucial aspect of user interaction, enhancing the overall driving experience and safety [39].
