In alot of the pictures there is a Moderator. The Moderator should have dealt with the situation.
Although there is a image where you are getting hit when your on the sidewalk and there should be no reason for a car to be on the sidewalk as much as you displayed.
Also there should not be a mutant in the car like Christopher said.

I would have to say to give him a small ban or a warning by talking to him in game and discuss this issue.
