Huajing S OTA Update: Smart Scenarios Add Experience, Child Forgetting Is Safety Baseline, But How Often Do Users Use Core Metrics?

In 2024, the number of OTA pushes for domestic new energy vehicles rose 47% year-over-year, yet the median weekly usage rate for users actively enabling smart scene features was only 12%. Meanwhile, there are still over a hundred heatstroke incidents annually caused by children being left in cars, while the penetration rate of truly deployable in-cabin vital sign monitoring solutions is less than 5%. Huajing S recently added "child forgotten alert" and multiple one-tap scene modes via OTA. On the surface, this looks like filling a gap, but as someone who deals with implementation details every day, I care more about: what are the detection rates and false positive rates of these features on actual vehicles, and does the trigger logic for scene modes really reduce user operational costs?
