"...Typically items in the trunk are deemed to be in the possession of the driver so while they're ok with you taking what's left of the wine bottle from the restaurant you have to have someone walk it home."
Not really. Just drive sanely, signal turns and lane changes, actually stop at stop signs and stoplights. A cop won't pull you over unless there's something resembling a cause that can justify the stop. The commonest reason for a stop is a "rolling stop" at an intersection. They also love catching people talking on their cell phone or better, texting. The fines are steep and contesting the ticket requires actual proof you were not using your cell phone.
