If I had a dollar for every time I was driving and I did not see a motorcyclist — for any number of variables — I would be a rich woman. They are a different size and shape than a car, and they are often in a different place (mid-lanes) than I expect a car to be.
I am a careful driver and I DO watch out for motorcyclists. If I were on a motorcycle, I would assume that NO driver ever saw me.
This poor guy.
One of my favorite hate visual things is first thing near dawn, a gray or black car driving to work with no lights on, on a gray or black road. I have also driven in pretty low light heavy rain and there is a pure gray car with no lights in the mist. But I expect this. As I said, there is a Bell Curve, and one out of two are in the bottom half. Expecting dumb, careless people to be smart careful people is crazy.
That is the only way to ride. I assume other drivers are going to hit me if I don't avoid them.
