My vote goes to too drunk to care. I'm going to go out on a limb and say this wasnt the first time Dunn got ripped, then went for a little drive.
I'm not going to say I'm glad hes dead, but I can say I'm glad he only took his passenger, who was equally drunk most likely, out with him. I certainly wont be shedding any tears for someone that gets hammered to the point they dont understand what they are doing and puts however many innocent lives at stake in the process.
