Very light traffic here as well - Long Island near NYC. So light I've seen my avg. speed pick up a good 1/2 mph as I generally slow and look at lights and proceed if clear. On Sat. there were far more people walking in the residential neighborhoods then driving and I really noticed that. OTOH, the MUP's and parks are jammed with people and the local governments are starting to crack down and close things up.

Thing about "stay at home" is it really means - in my mind, don't travel where you will be having many interactions with others. Go drive to a place where you generally will be alone if you get out and walk ?, I'm OK with that. I think that after 3 weeks now, people need to get out of the house for mental health reasons alone, just don't stop and chat. Make lunch at home, eat a picnic somewhere with nobody nearby.
