If you're going way too fast and not wearing enough protective gear while you're on a motorcycle, then you're just asking for trouble. One rider collided with the back end of a semi-truck and went flying. While we don't have any reports on injuries, it does appear that the rider was able to get up eventually.
Speaking of being reckless, you should always take a moment to look both ways when you come to an intersection. As can be seen on the dash cam, the driver in the darker car didn't slow down and ended up causing an accident. The driver of the darker car did try to plead their case, but the video is pretty conclusive.
