It's cost a lot of people a lot of money based on what it felt they "have to believe". The fact is it shouldn't be a DUI if you're found sleeping instead of driving drunk in your car.
Generally agree but what if you are found sleeping along the side of the road and the only way you could have gotten there is to drive? Sure, you made one good decision that you couldn't drive and pulled over... but you made a bad decision to drive in the first place so.... I would agree, as I stated above, that the good decision should at least be considered in the seriousness of the punishment.
Should you be punished for having a handgun in your glove compartment if you don't have a carry permit? It's harmless in the glove compartment, just like your car is harmless with you sleeping in it. It doesn't become a problem until you decide to use it....
