Google Earth is not updated all the time. The pictures on google street view can be old, with the stop sign and electric poles being a recent addition.
This can be a different sign on the google street view than the one in the video. I dont see the fire department in the photo w/ the ambulance, so I'm assuming it is a different intersection.
You need to think about probabilities here. Do you really think if someone was taking the time to fake a photo by adding an ambulance, they would also take the time to add a stop sign and electric poles?
You are all starting with the premise that this event did not really happen and working backwards trying to prove it. It is a biased and incorrect way to analyze reality. Additionally, you are all reinforcing one another's delusions with these ridiculous theories.
