Two cars returning to Santa Barbara after a day swimming in the upper Santa Ynez River sailed over the crest of the San Marcos Pass on Hwy 154 at ~75 - 80 mph.  We weren't racing and there wasn't any stodgy traffic that needed passing in the wide spot at the top of the hill, we were just travelling a familiar winding road at a fun speed.  We were driving Honda Civics.  I was in the car in front and my sister was about 6 car lengths behind.  With no traffic visable ahead we didn't let up much for the first turn—a gentle right.  As we zipped into the beginning of the turn we could begin to see what was beyond.  The entire 2 lanes of pavement was blocked by a wreck.  We braked heavily; which was kinda tricky since we had immediately moved to the unpaved shoulder to avoid any vehicles from behind that couldn't stop as fast as us.   It was a one car accident.  The 1970's Cadillac Coup de Ville was laying on its side, perpenicular to the roadway, steaming and smoking, blocking the whole roadway.  We came to a stop about 20' away.   The accident had obviously happened the very minute before.  I jumped out and started to run for the car.  I'd been an ambulance driver and open water lifeguard and always carried a 'seatbelt knife' for just these situations.  The fuel smell was heavy and the oil smoke was thick.  I thought it was probably going to burn.  I was concerned because I'd not yet seen the passengers and no one else was approaching the car to help.  I only went about 4 big steps when these four young guys hopped out through the driver's side windows.  They laughed hilariously.  The onlookers laughed.  I laughed.  I didn't need to tell them to stand clear and watch for downhill traffic coming around that blind curve, because they immediately rocked the car a little then pushed it back on its wheels.  They piled back in, and to everybody's amazement drove off, burning rubber, hooting and hollering out of sight.  In all, the whole event didn't take two minutes.  They didn't get the brand new car, but I've always felt that scene needed to be on a video of "Crawling from the Wreckage".
