I took CERT training about ten years ago. You‘re taught it’s very important to survey the scene before jumping into action. The heroic rescuers in this video were trying to open a door that was up against the guardrail.
One night about two years ago, I came upon a small SUV that had snapped off a utiility pole and continued downhill into a wooded, brushy area. Wires down, but I could see that they were the low comm wires, the three-phase lines were still attached to the top half of the pole which was hanging over the road. Driver’s door up against a tree. Passenger door and rear hatch jammed shut although the rear glass was broken out. The vehicle had a growing fire under the hood. The driver was a somewhat large woman who couldn’t get herself over the center console. Another passerby managed to crawl into the vehicle and recline her seat enough so that we could reach in an pull her out through the rear hatch.
