In Italy this question has been answered already. Riding a bike is proibito, whether on the trail or on the road, with a few exceptions. The general public can ride to get medical supplies or food, as long as they aren’t dressed like Marco Pantani. There is also an exemption for pro roadies. They must ride with their professional license with them and they are apparently forbidden by law from telling others they are allowed to ride because it is their profession, prompting many dirty looks. There is a fine of €3000 for violating these rules. The justification is that hospitals already overrun with COVID-19 patients have no space for busted cyclists who come limping in. And since that ban was enacted, Italians have been asked to stay at home entirely except to visit the doctor, pharmacy or supermarket. I don’t know anyone who would have predicted this would happen in my lifetime.
