I have mixed feeling about the entire situation as i was once in a similar circumstance. I once got a reckless driving citation for doing a burnout in my driveway. I never left my driveway, have no neighbors within a half a mile and my driveway is a good 1/8 th mile long. Highway patrol was driving by, saw me in mid burnout, pulled in with blue lights going and gave me the ticket. I was even going towards the house, not the road. The citation got tossed in court, but it still cost me the lawyers fees to deal with it.
That being said, i would never get behind the wheel of a vehicle with a drink in my hand, regardless of where i am or where i'm going. That move wasn't smart.
