"Procedures outside the stadiums and in the parking areas still need to be optimized, for example so that emergency medical services can leave the grounds on their way to the hospital faster"

This quote by Otto Schily suggests that treatments outside of arenas and in the parking areas require to be enhanced in order to ensure that emergency situation medical services can leave the premises rapidly and effectively. This could consist of simplifying the process of leaving the arena and parking areas, such as supplying clear signs and directions, or guaranteeing that emergency situation cars have top priority access to the roadways. Additionally, it could involve enhancing the facilities of the parking areas, such as expanding roadways or offering more parking areas. By optimizing these treatments, emergency medical services can leave the premises faster and more effectively, allowing them to reach the medical facility in a prompt manner and provide the needed treatment.
