So by your mental gymnastics, if a drunk driver is on the shoulder of the road and not the road, they're no longer a danger to those on the road, right?
I honestly have no idea what you're trying to argue any more. People with far more experience than you or I, with full knowledge of litigation in the state of New Jersey, are confident in their ability to define and prosecute/defend the laws regarding the use of bicycles while intoxicated in that jurisdiction. You don't have to accept it if you don't want to, but you certainly haven't been showing your work otherwise.
I personally don't even know if the Gaudreaus were confirmed to be under the influence in the first place. I'm not here to try and play internet lawyer with you. I'm not your enemy and nobody needs to be fabricating hostilities in a situation that is just ugly and shit all around. Can you just get off that train even for a minute?
