You definitely need to talk to someone who can help you get out of the situation. Maybe your minister? Or is there a teacher at your old high school that you trust?
Unfortunately, people with abusive tendancies don't usually get "better" without intervention, so I don't think you should count on him to outgrow the way he's acting. It's waaaaay beyond teenage brattiness. For goodness sake, the kid's old enough to drive and he's doing that?!?!?!?
According to your first post, you are 22. Will you be graduating soon? Is there anyone else you could stay with when you're not at school? It really sounds like you would be better off staying somewhere else.
I'm truly sorry about your situation
