my driving instructo told me that a complete stop is when you slighty jerk forward when stopping. esp. in the eyes of the cops.
LOL my car doesn't noticeably jerk forward anymore since I lowered it with Eibach Sporlines and stiffer KYB AGX shocks.
Of course I always stop my wheels from spinning at a stop sign, but more importantly I always look for cops lurking in the shadows. It pays to be paranoid.
