What aerodynamic and environmental hazard occurs when a heavy truck enters or exits a mountain highway tunnel at high speed ('tunnel portal gust' / 狭管效应)?

1. Sudden lateral wind gusts and lighting transition (black hole/white hole effect) can destabilize vehicle trajectory and impair driver vision
2. The atmospheric pressure drop inside the tunnel immediately punctures all tubeless tires
3. Tunnel ventilation exhaust gases cause immediate loss of engine compression
4. The change in electromagnetic field resets the digital tachograph clock
