What happen to an car scam driver who lies to the police, car insurance, investigator and to the other driver.?

based on the damage to both vehicles, it should be fairly easy for an honest investigator to determine what actually happened regardless of who lied. They will find out what it means to lie under oath or swear to false statements, and the guilty will be punished while the innocent will be vindicated. Hope you or someone took photos of the damage to both vehicles.
