The prosecutor would have to prove that you were driving, at some point in time, while under the influence of alcohol. For example, if a bartender testifies that he served you 10 shots of vodka between 1 and 2 am, and then the police find you 1 mile away sleeping in the car at 2:30 am, that is evidence that you drove 1 mile after drinking 10 shots. However if you were sleeping in the bar parking lot, with no evidence that you drove, then the prosecution would have no case.
