It is the fifth vehicle up from the left, if you include the first car for which you can only see the rear right bumper. This is row of cars along the building. View it on YouTube. There absolutely is someone in the car, and IMO opinion adjusting their rear view mirror and maybe even watching MC.
good catch. But playing Devils advocate, why didnt the car follow? Granted the video wasn't long but as MC was turning you would think the car would start to back out?
Defnitely interesting... Would love to see about 90 more seconds of that footage (before and after)
