Haha wow that's interesting, I used to do that but instead of using people I used some cones instead (those orange ones...I forgot what they're called for some reason) I just lined up a bunch of cones in front of the street. It was funny because people got out and moved them then after they left I put them back (I had some friends help me of course) and it was hilarious because I was collecting more cones with my friend when a car comes down the street towards us. I put down the cone and I start to casually walk down the sidewalk. There happened to be one cone in the crosswalk in front of the car that I "happened" to leave there but the funny thing was that the guy asked if I could move it for him and as he left he was like "Thank you!" Like super nice, he had no idea that I put it there in the first place haha. Eventually the cops came and put the cones on the sidewalk so I didn't want to take the chance of more cops coming and finding me so I stopped.
