Fuck karma, I hope I hear the crunch of collapsing asphalt and the grinding of shorn metal and torn gears as one of them falls through. I'll be the first to run out there and help, and then happily call emergency services to tell them that I'm here with "some jackass who thinks 'Road Closed' signs don't apply to him."
And yes, I've gone and shifted the barriers to make it a little harder to get in there. Not that it'll stop the SUV driving fucktards.
