My only real option to protect the scene and ourselves was to "take the lane" and block the road.
We dealt with patient care, spread absorbent down to catch the leaking fluids (from the cars, not the patients), disconnected battery cables, swept up glass and spare parts (again from vehicles not patients) and waited for the tow trucks. I was putting tools away on the traffic side of the engine when I noticed that the few cars had turned into twenty or more and were stretched all the way down the block and around the bend. The flatbeds were arriving to remove the cars and there was really no where for the cars to go but I still hustled back to the front of the engine to get away from the stares and questioning looks.
All in all these cars sat behind my engine on a residential street for about 35 minutes without even an option to bail out or turn around. Sorry about that folks. Cost of doing business I guess.
