What are some ways to stay safe while cycling on hospital routes, considering that emergency vehicles often have priority access and may not always follow traditional traffic rules, and hospital staff and visitors may be distracted or unfamiliar with local cycling infrastructure? Are there any specific safety precautions or strategies that cyclists can employ to mitigate the unique hazards associated with cycling near hospitals, such as navigating through crowded parking lots or avoiding pedestrians who may be preoccupied with their own health concerns? Do local cycling advocacy groups or hospital administrations provide any resources or guidelines for cyclists using hospital routes, and if so, what kinds of initiatives have been shown to be most effective in promoting cyclist safety in these areas?
