This is the closest I've ever come to a crash on my commute. Not on the 45mph busy arterial, but on the 25mph quiet residential street approaching a school zone.

I was traveling at 22-23mph before slowing hard. The 2nd driver missed me with about 4" to spare. That was the real hazard, the first older kid was showing off and was timing a near miss to get a rise out of me (successful). The 2nd was just following and it was lucky we didn't collide.
(note 2nd driver is only momentarily visible in the begining of video, but are out of frame when they nearly hit me. They basically took the same path as the first)
