Glad to hear you're OK.
It's just amazing the things we see. And while I too now hardly ever trust a driver or most bikers for that matter I am consistently surprised on just how close I come when I take all the precautions I can. Last night I was tooling up a fairly quiet road, had to make a left turn, moved from the center of the lane towards the middle stripe, stuck my hand out to make a left turn, I heard the PU truck behind me suddenly accelerate and then pass me on the left, my arm was still sticking out and I brushed the mirror as he went by. I watched him as he passed, he through up his hands in a "whaddya-expect-me-to-do" expression. He just HAD to pass me before I made my left hand turn and actually made him slow down. There was no oncoming traffic so I didn't even need to stop or slow down much to make the turn, he probably wouldn't of needed to even brake, just pull off the accelerator (if that even).
So be safe folks, trust no one, take all precaution and you'll mitigate SOME risk, but there are still a lot of people out there making some damn foolish decisions and remember WE will always lose when it comes to a collision.
