I do not see why that is infuriating; if two cars get in a wreck, we do not always cry out to fry the driver at fault unless they were doing something criminal.
We choose to ride motorcycles. we know that if we get in a wreck the would be minor for a car, it can be catastrophic for us. Why should the car driver get in more trouble because he failed to see a much smaller and harder to see target.
It is sad and my prayers go out to all the parties involved, but the driver of the truck made a mistake, and had he hit a Honda Accord, there would be no issue.
