My Father in law did a similar thing
as he flew into his driveway and took out the side of some jehovah's witnesse's car with the snowplow on the front of his truck. They tried to get him to pay for their car but he was so pissed off at them for being uninvited in his driveway then trying to get him to pay for their car that he billed them for damage to his snowplow. They never asked for money again or stopped by his house again.
