@aidan,
When Florida passed the no open alcohol containers in cars the police seems to be very eager to write tickets under that law.
My friend and fellow ultralight pilot was a complete non-drinker but he would used an insulated wrap around container to keep his coke cans cold that happen to have some beer brand letterings on it.
Base on this insulated container in his car cup holder with a beer adv on it he was stop by eager cops any numbers of times when the law was new.
He would let them go through a speach about the law no longer allowing him to have an open beer container in his car.
It was highly amusing for him to see the looks of disappointed on the cops faces when he would then pulled a coke can not a beer can from the insulation.
