Besides the legal issue is the perhaps more important issue that the reason for double yellow is most often due to danger of oncoming traffic so most drivers don't want to cross them anyway nor should they.
On a daily basis I observe drivers going around pedestrians, cyclists, postal vehicles, garbage trucks, utility vehicles, parking enforcement, and agricultural equipment in "no passing" zones, and that's including police vehicles with "drivers". The odds of needing to argue it in court are virtually nil unless a cop decides it was done in a dangerous manner.
