Maybe we could reclassify bars and homes as a closed circuit course (ex: race tracks) and have waivers signed upon entry. No direct liability to the provider of the event. Risk and responsibility to fall solely on Patron using facility, and there afterwards. Ya thats the answer lol
That works if one is on bar property when the damage is done, not unlike the track. However one usually has to cross public property leaving the bar and people on that property haven't signed any waivers nor should they be exposed to risks.
One unique thing about DWI is that unlike speeding, careless or dangerous driving, the drunk can't instantly be made into a safe driver with a lecture, threat of punishment or ticket.
