For night-time ride-hailing trips (e.g. between 23:00 and 05:00), what enhanced safety protection mechanisms are standardly deployed by platforms?

1. Mandatory cabin audio recording verification, passenger safety pin/facial verification, route deviation monitoring, and automated emergency contact sharing prompts
2. Turning off all vehicle headlights to conserve battery life
3. Requiring the driver to sing songs to keep the passenger awake
4. Tripling the speed limit to complete the trip faster
