That's one of my worst fears is to be hit from behind like that and not even see it coming. Hope the rider is okay.
That's an SV650, BTW.
My worst fear is when I'm on the line of a red light. I worry one of those people who flies towards a red light and cuts into the lane with the least amount of traffic isn't going to stop in time or at all. Constantly have my eyes looking back and keep myself ready to go right away.
