Please explain the video to me.

I think the video (and the song) is a metaphore of his drugs addiction.
He wants to leave it, but is not able to.

Him getting in the car is giving in to his addiction. He is 'loyal' to the drugs but wants to get rid of it and he is trying to end the addiction (choking the chick)..

It is not obvious and I am still trying to figure it out, but im pretty sure it is a methaphore on his addiction.

This video isn't made to be analyzed. It's made to just be whatever you see it as. It's art. There's no right or wrong theory; it's just how you view it.

I see it like a part of Eminem (the one in the backseat) knows that this relationship isn't going to end well, knows where things are headed, but Eminem doesn't care. He gets in the car anyway, taking a chance on love. Of course, things do end badly and then everything rewinds. I think that means that Em is thinking about what's going to happen when she stops and he steps in that car, and yet, he gets in anyway, leading to both of their inevitable doom. Just my theory.

The mental patient thing is awesome to me too. Pretty creative.
