Motorcycle Close Call (+ random)

First up, me nearly rear ending the car in front of me. Please note I knew straight away it would have been my fault. That swearing you hear is me getting angry at myself. Though, I was still frustrated with the car in front of me for changing their mind so suddenly. Second clip is a van failing to give way to a motorcycle at a "turn left any time with care" intersection. Third clip is a scooter lane splitting at pretty decent speeds. I'm a big supporter of lane filtering at stationary or slow moving traffic, but not sure how I feel about this one. Final clip is an example of a very classy man.
