Vehicle Traps and Staged Vehicular Setups

Here i could only describe what I witnessed was driving into a movie set full of obstacles. Broken down cars were staged in this little concentrated area like a obstacle course. The white vehicle parallel parking at the end of the video appears to be literally waiting for me to approach so I can accidentally hit it. I've never seen so many cars with hazards on like this accept when going to the airport. What the heck is going on here?
