I saw one of these guys driving one of those cars one morning when I came back home from taking my wife to school. (I work from home.) He waved at me and then parked out in front of my house for a while. I of course didn’t answer anything on the census except number of people in the house. He didn’t knock on our door or anything. I suppose he knows my race now since he saw me park there.
You are not on his list. If you answered the question of how many were in the house...you met your lawful duty.
