Core Viewpoint - The article discusses the growing concerns regarding panoramic sunroofs in electric vehicles, highlighting user complaints about excessive heat and inadequate protection from UV rays, which contradicts the technological promises made by car manufacturers [3][6][9]. Group 1: User Experience Issues - Users report that panoramic sunroofs act like "sun magnifiers," causing interior temperatures to soar, particularly affecting rear passengers [3][8]. - Despite claims that glass can block over 90% of UV rays, infrared radiation still penetrates, leading to discomfort and potential health risks for users [3][9]. - The design of some vehicles eliminates sun visors to enhance visibility, further exacerbating the issue of sun exposure for drivers [9][11]. Group 2: Industry Response and Standards - The Ministry of Industry and Information Technology has initiated a review of safety standards for hidden door handles, indicating a broader trend of regulatory scrutiny in the automotive sector [4][6]. - There is a call for new standards regarding the thermal performance and UV protection of panoramic roofs, similar to existing regulations for side windows [13][14]. - Some companies are exploring innovative solutions like variable light transmission roofs and temperature control technologies to address user concerns [11][14]. Group 3: Market Dynamics and Competitive Advantage - Panoramic sunroofs have become a standard feature in many electric vehicles, appealing to younger consumers seeking a futuristic aesthetic [6][8]. - The cost advantages of panoramic roofs, such as reduced component count and assembly efficiency, make them attractive for manufacturers in a competitive market [6][8]. - The potential for increased vehicle pricing by over 5,000 yuan due to the inclusion of panoramic roofs highlights their perceived value in differentiation strategies [6][8].

Core Viewpoint - The article discusses the tension between technological features and user experience in the automotive industry, highlighting the need for optimization of certain features that are currently seen as unnecessary or problematic by consumers [1][20]. Group 1: Panoramic Sunroofs - Panoramic sunroofs are becoming standard in electric vehicles, enhancing headroom and providing a scenic view, but they can lead to excessive heat in summer, making the driving experience uncomfortable [2][3][7]. - Many consumers report that the large glass surface of panoramic sunroofs acts like a "solar collector," significantly increasing cabin temperatures, which has led to complaints on social media [3][7]. - The trend of using panoramic sunroofs is not limited to electric vehicles; even traditional fuel cars like the latest Toyota Camry and Ford Mondeo are adopting this feature [7]. - Engineers note that panoramic sunroofs save space and reduce vehicle weight, which can help improve electric vehicle efficiency, with costs for panoramic glass being lower than traditional sunroofs [8][11]. - Despite claims of UV protection, panoramic sunroofs do not effectively block infrared rays, which contribute to heat buildup in the cabin [11]. - Consumers are resorting to various methods to mitigate heat, including installing sunshades or using makeshift solutions like newspapers, which can lead to increased energy consumption due to higher air conditioning use [12][17][18]. Group 2: Disappearing Physical Buttons - The trend of replacing physical buttons with touchscreens, initiated by Tesla, is becoming prevalent in the automotive industry, with many new models lacking any physical controls [20][21]. - Research indicates that using touchscreens can significantly increase driver reaction times, raising safety concerns compared to traditional physical controls [22][24]. - A study showed that drivers using older vehicles with physical buttons could complete tasks much faster than those using modern touchscreens, which can take significantly longer [24]. - Issues with touchscreen systems, such as system failures, have raised concerns about the reliability of vehicles that depend heavily on electronic controls [24]. - Some manufacturers are beginning to reintroduce physical buttons in response to consumer feedback, emphasizing the importance of balancing technology with user experience [25][26]. - The article concludes that while innovative designs are important, safety and user experience should remain the top priorities in automotive design [27].
