Seen that video before. If the car filming it hadn't chased after the person committing the hit and run and filmed the driver, who's to say that the guilty party wouldn't deny it and make up a claim about it not being them behind the wheel / it was stolen. They may have got away with it if it...
Simple question then, why didn't the motorist stop? they would have known that they had hit someone
The cyclist has posted this because they are frustrated that someone has gotten away with this (at a minimum, failing to stop following an accident)
It shows that someone can get run over...
