The problem with this highway interchange is that both lanes have to cross over. One left to right (the other driver) and one right to left (me). I attached a diagram of what happened. The car was traveling west on 85 and was transitioning to south on 17. I was traveling north on 17 and transitioning to west on 85. In the image, I am the blue line and the car is the red line. The car changed lanes early across the solid white line and hit me at the red X. She pulled over at the place marked X1 and I pulled in behind her. She then started up and I thought it was going to be a hit and run but she stopped again at the spot marked X2 because, as she put it, "it was safer further from the curve."
The points on my side are that 1) I could see her while I was in the turn; 2) Unless she looked up the hill, she may not have seen me; 3) I was in a right hand curve and as you know, on a bike, you hug the inside corner; 4) By the the time I exit the corner and was beside the car, I was in their blind spot; 5) If I had crossed the line and hit them, not only would the damage pattern been different, but the car could not have pulled over so quickly.
It's frustrating to have to battle it out, but if it ever happens again (hope not!) I just installed the cameras from and back.
V-Tom: I also fly hang gliders and constantly check the accident reports for the very same reason. In this case, perhaps if I had watched the car and had been a little more proactive. They were passing me and I expected that they would cross lanes but didn't expect them to do it so soon. The fact that I was able to stay up I attribute to it being a glancing blow and that I have been riding for a long time. When I was hit, I wasn't thinking "I've been hit!" but rather "Stay up, stay up, STAY UP!"
Ride safe. Cheers!
