Core Viewpoint - The article discusses the conditions necessary for urban autonomous driving to reach early adopters, emphasizing the importance of stable merging capabilities as a tool-like attribute for users [1]. Group 1: Hypothesis and Definitions - Hypothesis: Urban autonomous driving will reach early adopters when it possesses tool-like attributes during peak traffic hours [1]. - Definition of Tool-like Attributes: 40% of drivers can master over 95% of autonomous driving capabilities within three days of deliberate practice, ensuring comfort and safety [1]. - Definition of Stable Merging Ability: Users can successfully merge in 99% of scenarios when required to maintain navigation, ensuring comfort and peace of mind [1]. Group 2: Judgments on Urban Autonomous Driving - Judgment 1: Vehicles with stable merging capabilities will demonstrate advanced spatial-temporal planning abilities, crucial for urban driving [2]. - Judgment 2: Challenges such as unprotected left turns and narrow road encounters do not significantly impact the tool-like nature of autonomous driving, while stable merging is critical [2]. - Judgment 3: No domestic automaker, including Li Auto, has effectively showcased stable merging capabilities in promotional materials, with current capabilities being average in congested conditions [2]. - Judgment 4: Early adopters often take control in challenging scenarios, indicating a gap in user acceptance of autonomous driving tools [2]. Group 3: Technical Insights - Li Auto's current best computing platform operates at 10 Hz with a 40 billion parameter model, while the execution system runs at 60 Hz; improvements in model speed could enhance comfort and responsiveness in autonomous driving [4]. - The human reaction time for braking and steering is around 450 milliseconds, while the current autonomous driving response time is approximately 550 milliseconds; advancements in control systems could reduce this to 350 milliseconds, potentially halving accident rates [4]. - Li Auto may develop a preliminary form of stable merging capabilities in the future [5].
