Full Lifecycle Security: Sensor Aging Curves and OTA Rollback Rates, Not Just Slogans

Academician Li Jun's mention of "full lifecycle safety" at the 2026 China Auto Forum sounds like a platitude, but if you've seen the hardware degradation data from current mass-produced autonomous vehicles, you know this phrase hides the industry's biggest engineering headache. Safety first isn't a slogan; it requires quantitative commitments regarding the noise levels of every LiDAR unit after 100,000 hours, solder joint fatigue in every domain controller under high heat and humidity, and system rollback rates after each OTA update. Currently, the gap between the two technical routes in the industry along the "full lifecycle" dimension is wider than many people imagine.
