When just looking at the raw statistics for motorcycle accidents, the numbers are dwarfed by car accidents, both fatal and otherwise. However, this can skew perceptions somewhat. There are far more cars on the roads than motorcycles, so the numbers are bound to be higher. That doesn't really tell you much about how relatively dangerous motorcycles are. For that, it can be better to look at the percentages.
Auto-pedestrian accidents involving a hit-and-run can be admittedly tricky. Sometimes, the driver that caused the accident cannot be found, leaving injured pedestrians at a loss for seeking the compensation they need. Without financial recovery, they are often unable to pay for medical treatment and other expenses related to their injuries.
