When driving a commercial coach (Category D) on a mountain route, how should the driver manage passenger comfort and safety around sharp switchbacks?

1. Decelerate smoothly before each curve, maintain steady line without jerky steering, avoid abrupt braking, and ensure all passengers remain seated with seatbelts fastened
2. Drive aggressively around corners so centrifugal force pins passengers to their seats
3. Encourage passengers to stand and lean out of the windows to balance the bus
4. Shift into neutral and coast silently around corners
