It's car free Sunday here in Belgium and the streets are a treat to navigate. Cycling is actually slower than usual since there are so many people constantly on the streets, many of them pedestrians or roller skaters.
But it's .. safe. Nice. Breathable. Not that Brussels isn't those things normally but today more than usual.
