## 根因

汽车空调内循环无法过滤野火烟雾中的一氧化碳和氰化氢等有毒气体，且车辆金属车身传导辐射热，导致车内温度在几分钟内升至致命水平。

## 解决方案

1. ```
   Evacuate the area before the fire arrives. If trapped, park in an area clear of vegetation (e.g., parking lot), close all windows, turn off engine, lie on the floor, and cover with a wool blanket. Call 911.
   ```
2. ```
   If possible, abandon the car and move to a previously burned area or a body of water. Never stay in a car surrounded by flames.
   ```

## 无效尝试

- **Turning on AC recirculation mode and covering vents with wet towels to filter smoke** — Wet towels block airflow but do not filter CO; the car quickly fills with toxic gas and heat. (80% 失败率)
- **Staying in the car with windows up and engine off to avoid drawing in smoke** — Radiant heat from the fire will still heat the car interior to over 150°F, causing heatstroke. (90% 失败率)
- **Driving through the fire front at high speed to escape** — Fire fronts move faster than cars in many cases; the car may stall or catch fire from embers. (75% 失败率)
