TBH, nit sure what the point of these post mortems is supposed to be. I don't know that there's a lesson to be drawn from a situation involving fluke timing that you probably couldn't duplicte if you tried. I'd like to think that I'd have been into the left turn lane earlier than you were so that the car behind the pickup would have more than enough warning I was there but, not having been there, I think this is just 20/20 hindsight at best.
