This happened to me last weekend too! Except it was someone in a Nissan Quest!
I was on the backroads with my gf when we run into some traffic. A Nissan Pathfinder was holding up traffic and not turning off to let any one by. It was Pathfinder, Quest, and me in the back.
All of a sudden, the Quest crosses the double yellows and floors it going up hill. My GF and I were both like "WHOA WTF" and that's when on coming traffic emerged, forcing the Pathfinder to brake so the Quest had enough time to move back over.
That's up there for one of the dumbest driver's I've ever seen.
Eventually the Pathfinder gets the picture and lets me by. I catch up to the Quest, and he doesn't let me by, instead increasing his speed through the turns. GUY WAS CANYON CARVING IN A MINIVAN.
At this point, I'm not even mad and I'm enjoying watching the steel whale of a car tilt in the corners. I eventually take another road and went on my way.
I was speechless.
