A: Good response given the driving conditions, I would have done the same thing albeit slightly slower given I'd be in an engine, and only due to width and lack of accelleration.
B: I was surprised you didn't touch the e-horn once, but it's your first due and you know what people do there for various things. Either me, or my right seater, would have been LAYING on the air horn with the amount of "don't give a" drivers... window down, doesn't pull over, etc.
In my best Sam Kinison voice: AAAAGH! People are soooo stupid! When you see flashing lights and hear a siren you are supposed to get out of the way!
Oh, nice video and I've heard the Rumbler a few times, I like it. It really vibrates and will get people's attention. The people just need to learn to get out of the freaking way! AAAAAGH!
In the beginning of the video there was a car that was pulling over to yield and he came right on the cars rear and blasted his horn. Unnecessary in my opinion. I also thought he was passing the stopped traffic kinda fast but maybe its just the camera. I know cameras distort speed and distance.
