Question about damage handling!

Accident: Two vehicles touch each other in the oncoming traffic (Landstrasse) with the exterior mirrors that also break and damage the side window and the paint of the door in a vehicle. A driver drives on without stopping, the second turns and drives after him, picks him up and moves him to stop with the light horn and horn. To the question whether he has not noticed the accident he twitches with the armpits gives gas and drives on again. In the meantime, it is known that the driver is searching for the address within a short time, and the damaged car is also examined – rings – but nobody opens it. What are the chances of getting the damage from the driver’s fugitive? or does his insurance want to refuse to accept any damage due to the driver’s flight (which was also confirmed by the police in writing). Does not always pay the liability and demand the amount back in regress? Thanks leo
