Couple of things I noticed here that led the the crash:
1: False sense of security riding 3rd in line,no adjustment in lane to allow a longer field of view.
2: As others noted, truck blocking view.
3: Never hesitated coming up to intersection.
4: Assumed the driver was going to SEE him....(Hello...anyone there?)
5: Lead driver needs to be able to recognized trouble, I always believed as the lead rider, you can assist those you ride with in safety. (He never slowed as well with limited view)
6: Failed to react, and process the evolving situation, there where numerous red flags leading up to the crash, and should have been easily avoided, leaving just a blurp out of the fullface as he rode by...FYYFF!
For many long time riders, these issues are readily processed over and over during the ride,others have been just lucky, his luck ran out.
2 years ago,I got the bike out on a spring day after a long winter, feeling abit rusty and not in my summer grove I tooled along at 10mph over the speed limit on a sunny day. Running 45 in a 35, I rounded a blind turn, I was huggung the double yellow as it opened up my view due to a steep bank on the inside of the turn....Well to my surprise, a friggin school bus was stopped dead in my lane, about 3/4 through the turn, letting little rugrats off.
I straighten the machine up, grabbed a handfull of front brake and nailed the rear in an instant...I then processed I was not going to be able to stop in time, at the same instant I was processing that, I was looking for an out. Due to my lane of travel on the double yeller, I then saw the swing gate down for oncoming traffic, swung wide of the bus into the oncoming lane, still under braking. I was able to pull off the road about half the bus length.
I think back about the train of thought that took place, access, recogize, and solve, it amazed me how fast I was able to prcess all the information.
This took everybit of about 8 seconds, from the time I saw the bus, until I stopped the machine ( seemed to be less than that, I could not have been more than 35' from the ass of that thing when i first saw it). If I had been on the outside of the turn, I am fairly sure the outcome would have been very different. I do not think the bus stops in the same spot anymore as I am sure the driver was looking at me in the review side mirror. It registered a very firm 8.0 on the sphincter factor
