Under what condition is livestock transport (transporte de ganado en pie) particularly hazardous during cornering and braking?

1. Livestock remain completely stationary at all times
2. Live animals move unpredictably inside the cattle body, shifting their collective weight to the outside of curves or forward during braking, creating severe dynamic center of gravity surges
3. Livestock generate electromagnetic interference with the tachograph
4. Livestock reduce the vehicle's braking distance by 30%
