I think it should be. The manner of driving to me is much more important than the state of a driver's mind.
If the driver had a .01 BAC but was driving "carefully" and just suddenly lost control of the car, you would not punish him as much as you would a sober guy who was driving 15 miles per hour over the speed limit when his front tire blew out and he lost control of the car and crossed the center divider and plowed into that same car.
Have I got it right?
BTW how many DUI's have you had?
