The 1st crash the marshal looked like,eshe was helping smallkid cross the road just tell the driver were to go you don't need to hold there arms a walk them across the road.
the marshals in croatia were mostly overwhelmed with their work. Some Barriers, especially at jumps were senseless and completely wrong. After the jump, you need space, not at the jump 🤦♂️ Too few professional safety marshals, too much volunteers.
