I assure you that if you jump in front of a moving train you will be killed. How is this different?

[princeb]

cars are not trains, for one.

road usage is shared among cars, motorcycles and scooters, trucks, pedestrians, bicycles, mobility scooters, and other things.

[akkat]

Train tracks are also shared at train crossings. Yet if a car went there after the warning lights went on, the car would be to blame.

The main difference is that a train, even under emergency braking, can't stop quickly, and it also can't swerve to avoid an obstacle. If you jump in front of a moving train, even if the train driver could see you before you jumped and could predict you would jump, you will get hit.
