Yeah, I agree- I’m pretty sure the horn was from the BMW. He was probably protesting because he had more right-of-way than the school bus did in the first few seconds of the video. The camera-car was not only illegally “directing traffic”, but also creating a lot of hesitation that was holding up traffic even more…

This deserves more stars. When people stop in the middle of the road to let jay walker by, things get nasty and rear ending can happen, Same for all other courtesy.

If that is the case the dashcam owner practices backwards courtesy which is a leading cause of congestion, annoyance, and collisions. Backward courtesy is where the person practicing it decides to be nice to person A at the expense of person B instead of following the written rules of the road.
